- LM386 Low Voltage Audio Power Amplifier
The LM386 is a power amplifier designed for use in low voltage consumer applications.
The gain is internally set to 20 tokeep external part count low, but the addition of an external
resistor and capacitor between pins 1 and 8 will increase the gain to any value from 20 to 200.
The inputs are ground referenced while the output automatically biases to one-half the supply voltage.
The quiescent power drain is only 24 milliwatts when operating from a 6 volt supply, making the
LM386 ideal for battery operation.

The LM139 series consists of four independent precisionvoltage comparators with an offset voltage
specification as low as 2 mV max for all four comparators. These weredesigned specifically to operate
from a single power supply over a wide range of voltages. Operation from split power supplies is also
possible and the low power supply current drain is independent of the magnitude of the power supply

The LM111, LM211 and LM311 are voltage comparators that have input currents nearly a thousand times

Their output is compatible with RTL, DTL and TTL as well as MOS circuits. Further, they can drive
lamps or relays, switching voltages up to 50V at currents as high as 50 mA. Both the inputs and
the outputs of the LM111, LM211 or the LM311 can be isolated from system ground, and the output can
drive loads referred to ground, the positive supply or the negative supply. Offset balancing and
strobe capability are provided and outputs can be wire OR’ed. Although slower than the LM106 and

industry standards like the LM709. They are direct, plug-in replacements for the 709C, LM201,
MC1439 and 748 in most applications. The amplifiers offer many features which make their application
nearly foolproof: overload protection on the input and output, no latch-up when the common mode
range is exceeded, as well as freedom from oscillations. The LM741C is identical to the LM741/LM741A
except that the LM741C has their performance guaranteed over a 0°C to +70°C temperature range,
instead of -55°C to +125°C.

Further, the class-B output stage gives a large output capability with minimum power drain. External
components are used to frequency compensate the amplifier. Although the unity-gain compensation
network specified will make the amplifier unconditionally stable in all feedback configurations,
compensation can be tailored to optimize high-frequency performance for any gain setting. The
LM709C is the commercial-industrial version of the LM709. It is identical to the LM709 except
that it is specified for operation from 0°C to +70°C.

- LM158/LM258/LM358/LM2904 Low Power Dual Operational Amplifiers
The LM158 series consists of two independent, high gain, internally frequency compensated
operational amplifiers which were designed specifically to operate from a single power supply
over a wide range of voltages. Operation from split power supplies is also possible and the low
power supply current drain is independent of the magnitude of the power supply voltage. Application
areas include transducer amplifiers, dc gain blocks and all the conventional op amp circuits which
now can be more easily implemented in single power supply systems. For example, the LM158 series
can be directly operated off of the standard +5V power supply voltage which is used in digital
systems and will easily provide the required interface electronics without requiring the
additional ±15V power supplies. The LM358 and LM2904 are available in a chip sized package
(8-Bump micro SMD) using National’s micro SMD package technology.
Unique Characteristics: In the linear mode the input common-mode voltage range includes
ground and the output voltage can also swing to ground, even though operated from only a single
power supply voltage. The unity gain cross frequency is temperature compensated. The input
bias current is also temperature compensated.
Advantages: Two internally compensated op amps; Eliminates need for dual supplies; Allows
direct sensing near GND and VOUT also goes to GND; Compatible with all forms of logic; Power
drain suitable for battery operation; Pin-out same as LM1558/LM1458 dual op amp.

operational amplifiers which were designed specifically to operate from a single power supply over
a wide range of voltages. Operation fromsplit power supplies is also possible and the low power
supply current drain is independent of the magnitude of the power supply voltage. Application areas
include transducer amplifiers, DC gain blocks and all the conventional op amp circuits which now can

- LM148 Low Power Quad Operational Amplifiers
The LM148 series is a true quad 741. It consists of four independent, high gain, internally
compensated, low power operational amplifiers which have been designed to provide functional
characteristics identical to those of the familiar 741 operational amplifier. In addition the
total supply current for all four amplifiers is comparable to the supply current of a single 741
type op amp. Other features include input offset currents and input bias current which are much
less than those of a standard 741. Also, excellent isolation between amplifiers has been achieved
by independently biasing each amplifier and using layout techniques which minimize thermal coupling.
The LM148 can be used anywhere multiple 741 or 1558 type amplifiers are being used and in
applications where amplifier matching or high packing density is required. For lower power refer

- LM112/LM212/LM312 Operational Amplifiers
The LM112 series are micropower operational amplifiers with very low offset-voltage and
input-current errors–at least a factor of ten better than FET amplifiers over a -55°C to +125°C
temperature range. Similar to the LM108 series, that also use supergain transistors, they differ
in that they include internal frequency compensation and have provisions for offset adjustment
with a single potentiometer. These amplifiers will operate on supply voltages of +-2V to +-20V,
drawing a quiescent current of only 300 mA. Performance is not appreciably affected over this
range of voltages, so operation from unregulated power sources is easily accomplished. They can
also be run from a single supply like the 5V used for digital circuits. The LM112 series are the
first IC amplifiers to improve reliability by including overvoltage protection for the MOS
compensation capacitor. Without this feature, IC's have been known to suffer catastrophic
failure caused by short-duration overvoltage spikes on the supplies. Unlike other internally-
compensated IC amplifiers, it is possible to overcompensate with an external capacitor to increase
stability margin. The LM212 is identical to the LM112, except that the LM212 has its performance
guaranteed over a -25°C to +85°C temperature range instead of -55°C to +125°C. The LM312 is
guaranteed over a 0°C to +70°C temperature range.
Features: Maximum input bias current of 3 nA over temperature;
Offset current less than 400 pA over temperature; Low noise; Guaranteed drift specifications
- LM146/LM346 Programmable Quad Operational Amplifiers
The LM146 series of quad op amps consists of four independent, high gain, internally compensated,
low power, programmable amplifiers. Two external resistors (RSET) allow the user to program the gain
bandwidth product, slew rate, supply current, input bias current, input offset current and input
noise. For example, the user can trade-off supply current for bandwidth or optimize noise figure
for a given source resistance. In a similar way, other amplifier characteristics can be tailored
to the application. Except for the two programming pins at the end of the package, the LM146 pin-out
is the same as the LM124 and LM148.

- LM340/LM78XX Series 3-Terminal Positive Regulators
(7805 / 7806 / 7808 / 7812 / 7815)
General Description: The LM140/LM340A/LM340/LM78XXC monolithic 3-terminal positive voltage
regulators employ internal current-limiting, thermal shutdown and safe-area compensation, making
them essentially indestructible. If adequate heat sinking is provided, they can deliver over 1.0A
output current. They are intended as fixed voltage regulators in a wide range of applications
including local (on-card) regulation for elimination of noise and distribution problems associated
with single-point regulation. In addition to use as fixed voltage regulators, these devices can be
used with external components to obtain adjustable output voltages and currents. Considerable effort
was expended to make the entire series of regulators easy to use and minimize the number of external
components. It is not necessary to bypass the output, although this does improve transient response.
Input bypassing is needed only if the regulator is located far from the filter capacitor of the power
supply. The 5V, 12V, and 15V regulator options are available in the steel TO-3 power package.
The LM340A/LM340/LM78XXC series is available in the TO-220 plastic power package, and the LM340-5.0
is available in the SOT-223 package, as well as the LM340-5.0 and LM340-12 in the surface-mount

- LM79XX Series 3-Terminal Negative Regulators
(7905 / 7906 / 7908 / 7912 / 7915)
General Description: The LM79XX series of 3-terminal regulators is available with fixed output
voltages of -5V, -12V, and -15V. These devices need only one external component—a compensation
capacitor at the output. The LM79XX series is packaged in the TO-220 power package and is capable
of supplying 1.5A of output current. These regulators employ internal current limiting safe area
protection and thermal shutdown for protection against virtually all overload conditions. Low ground
pin current of the LM79XX series allows output voltage to be easily boosted above the preset value
with a resistor divider. The low quiescent current drain of these devices with a specified maximum
change with line and load ensures good regulation in the voltage boosted mode. For applications
requiring other voltages, see LM137 datasheet.
Features: Thermal, short circuit and safe area protection; High ripple rejection;
1.5A output current; 4% tolerance on preset output voltage.
- LM109/LM309 5-Volt Regulator

Internal thermal overload protection; No external components required.
- LM117/LM317A/LM317 3-Terminal Adjustable Regulator
General Description: The LM117 series of adjustable 3-terminal positive voltage regulators is
capable of supplying in excess of 1.5A over a 1.2V to 37V output range. They are exceptionally easy
to use and require only two external resistors to set the output voltage. Further, both line and
load regulation are better than standard fixed regulators. Also, the LM117 is packaged in standard
transistor packages which are easily mounted and handled. In addition to higher performance than
fixed regulators, the LM117 series offers full overload protection available only in IC’s. Included
on the chip are current limit, thermal overload protection and safe area protection. All overload
protection circuitry remains fully functional even if the adjustment terminal is disconnected.
Normally, no capacitors are needed unless the device is situated more than 6 inches from the input
filter capacitors in which case an input bypass is needed. An optional output capacitor can be added
to improve transient response. The adjustment terminal can be bypassed to achieve very high ripple
rejection ratios which are difficult to achieve with standard 3-terminal regulators. Besides
replacing fixed regulators, the LM117 is useful in a wide variety of other applications. Since the
regulator is "floating" and sees only the input-to-output differential voltage, supplies
of several hundred volts can be regulated as long as the maximum input to output differential is not
exceeded, i.e., avoid short-circuiting the output. Also, it makes an especially simple adjustable
switching regulator, a programmable output regulator, or by connecting a fixed resistor between
the adjustment pin and output, the LM117 can be used as a precision current regulator. Supplies with
electronic shutdown can be achieved by clamping the adjustment terminal to ground which programs the
output to 1.2V where most loads draw little current. For applications requiring greater output
current, see LM150 series (3A) and LM138 series (5A) data sheets. For the negative complement, see
LM137 series data sheet.

than standard fixed regulators. Also, the LM317L is available packaged in a standard TO-92 transistor
package which is easy to use. In addition to higher performance than fixed regulators, the LM317L

and safe area protection. All overload protection circuitry remains fully functional even if the

regulators are exceptionally easy to apply, requiring only 2 external resistors to set the output
voltage and 1 output capacitor for frequency compensation. The circuit design has been optimized for
excellent regulation and low thermal transients. Further, the LM137 series features internal current
limiting, thermal shutdown and safe-area compensation, making them virtually blowout-proof against
overloads. The LM137/LM337 serve a wide variety of applications including local on-card regulation,
programmable-output voltage regulation or precision current regulation. The LM137/ LM337 are ideal

regulator applications. By itself, it will supply output currents up to 150 mA; but external
transistors can be added to provide any desired load current. The circuit features extremely low
standby current drain, and provision is made for either linear or foldback current limiting. The
LM723/LM723C is also useful in a wide range of other applications such as a shunt regulator, a
current regulator or a temperature controller. The LM723C is identical to the LM723 except that
the LM723C has its performance guaranteed over a 0°C to +70°C temperature range, instead of -55°C
Features: 150 mA output current without external pass transistor; Output currents in excess
of 10A possible by adding external transistors; Input voltage 40V max;Output voltage adjustable
from 2V to 37V; Can be used as either a linear or a switching regulator.
