LM158/LM258/LM358/LM2904
Low Power Dual Operational Amplifiers
General Description
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 is also available in a chip sized package
(8-Bump micro SMD) using National’s micro SMD package
technology.
Unique Characteristics
n 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.
n The unity gain cross frequency is temperature
compensated.
n The input bias current is also temperature compensated.
Advantages
n Two internally compensated op amps
n Eliminates need for dual supplies
n Allows direct sensing near GND and VOUT also goes to
GND
n Compatible with all forms of logic
n Power drain suitable for battery operation
n Pin-out same as LM1558/LM1458 dual op amp
Features
n Available in 8-Bump micro SMD chip sized package,
(See AN-1112)
n Internally frequency compensated for unity gain

n Wide bandwidth (unity gain): 1 MHz
(temperature compensated)
n Wide power supply range:
— Single supply: 3V to 32V
— or dual supplies: ±1.5V to ±16V
n Very low supply current drain (500 µA) — essentially
independent of supply voltage
n Low input offset voltage: 2 mV
n Input common-mode voltage range includes ground
n Differential input voltage range equal to the power
supply voltage
n Large output voltage swing: 0V to V+− 1.5V

Note 1: For operating at high temperatures, the LM358/LM358A, LM2904 must be derated based on a +125˚C maximum junction temperature and a thermal
resistance of 120˚C/W for MDIP, 182˚C/W for Metal Can, 189˚C/W for Small Outline package, and 230˚C/W for micro SMD, which applies for the device soldered in
a printed circuit board, operating in a still air ambient. The LM258/LM258A and LM158/LM158A can be derated based on a +150˚C maximum junction temperature.
The dissipation is the total of both amplifiers — use external resistors, where possible, to allow the amplifier to saturate or to reduce the power which is dissipated
in the integrated circuit.
Note 2: Short circuits from the output to V+ can cause excessive heating and eventual destruction. When considering short cirucits to ground, the maximum output
current is approximately 40 mA independent of the magnitude of V+. At values of supply voltage in excess of +15V, continuous short-circuits can exceed the power
dissipation ratings and cause eventual destruction. Destructive dissipation can result from simultaneous shorts on all amplifiers.
Note 3: This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP
transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also lateral NPN parasitic transistor action on
the IC chip. This transistor action can cause the output voltages of the op amps to go to the V+voltage level (or to ground for a large overdrive) for the time duration
that an input is driven negative. This is not destructive and normal output states will re-establish when the input voltage, which was negative, again returns to a value
greater than −0.3V (at 25˚C).
Note 4: These specifications are limited to −55˚C ≤ TA ≤ +125˚C for the LM158/LM158A. With the LM258/LM258A, all temperature specifications are limited to −25˚C
≤ TA ≤ +85˚C, the LM358/LM358A temperature specifications are limited to 0˚C ≤ TA ≤ +70˚C, and the LM2904 specifications are limited to −40˚C ≤ TA ≤ +85˚C.
Note 5: VO . 1.4V, RS = 0Ω with V+ from 5V to 30V; and over the full input common-mode range (0V to V+ −1.5V) at 25˚C. For LM2904, V+ from 5V to 26V.
Note 6: The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output so
no loading change exists on the input lines.
Note 7: The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V (at 25˚C). The upper end of the
common-mode voltage range is V+ −1.5V (at 25˚C), but either or both inputs can go to +32V without damage (+26V for LM2904), independent of the magnitude of
V+.
Note 8: Due to proximity of external components, insure that coupling is not originating via stray capacitance between these external parts. This typically can be
detected as this type of capacitance increases at higher frequencies.
Note 9: Refer to RETS158AX for LM158A military specifications and to RETS158X for LM158 military specifications.

Typical Performance Characteristics (Continued)
Application Hints
The LM158 series are op amps which operate with only a
single power supply voltage, have true-differential inputs,
and remain in the linear mode with an input common-mode
voltage of 0 VDC. These amplifiers operate over a wide range
of power supply voltage with little change in performance
characteristics. At 25˚C amplifier operation is possible down
to a minimum supply voltage of 2.3 VDC.
Precautions should be taken to insure that the power supply
for the integrated circuit never becomes reversed in polarity
or that the unit is not inadvertently installed backwards in a
test socket as an unlimited current surge through the result-
ing forward diode within the IC could cause fusing of the
internal conductors and result in a destroyed unit.
Large differential input voltages can be easily accomodated
and, as input differential voltage protection diodes are not
needed, no large input currents result from large differential
input voltages. The differential input voltage may be larger

than V+ without damaging the device. Protection should be
provided to prevent the input voltages from going negative
more than −0.3 VDC (at 25˚C). An input clamp diode with a
resistor to the IC input terminal can be used.
To reduce the power supply current drain, the amplifiers
have a class A output stage for small signal levels which
converts to class B in a large signal mode. This allows the
amplifiers to both source and sink large output currents.
Therefore both NPN and PNP external current boost transis-
tors can be used to extend the power capability of the basic
amplifiers. The output voltage needs to raise approximately
1 diode drop above ground to bias the on-chip vertical PNP
transistor for output current sinking applications.
For ac applications, where the load is capacitively coupled to
the output of the amplifier, a resistor should be used, from
the output of the amplifier to ground to increase the class A
bias current and prevent crossover distortion. Where the
load is directly coupled, as in dc applications, there is no
crossover distortion.
Capacitive loads which are applied directly to the output of
the amplifier reduce the loop stability margin. Values of 50
pF can be accomodated using the worst-case non-inverting
unity gain connection. Large closed loop gains or resistive
isolation should be used if larger load capacitance must be
driven by the amplifier.
The bias network of the LM158 establishes a drain current
which is independent of the magnitude of the power supply
voltage over the range of 3 VDC to 30 VDC.
Output short circuits either to ground or to the positive power
supply should be of short time duration. Units can be de-
stroyed, not as a result of the short circuit current causing
metal fusing, but rather due to the large increase in IC chip
dissipation which will cause eventual failure due to exces-
sive function temperatures. Putting direct short-circuits on
more than one amplifier at a time will increase the total IC
power dissipation to destructive levels, if not properly pro-
tected with external dissipation limiting resistors in series
with the output leads of the amplifiers. The larger value of
output source current which is available at 25˚C provides a
larger output current capability at elevated temperatures
(see typical performance characteristics) than a standard IC
op amp.
The circuits presented in the section on typical applications
emphasize operation on only a single power supply voltage.
If complementary power supplies are available, all of the
standard op amp circuits can be used. In general, introduc-
ing a pseudo-ground (a bias voltage reference of V+/2) will
allow operation above and below this value in single power
supply systems. Many application circuits are shown which
take advantage of the wide input common-mode voltage
range which includes ground. In most cases, input biasing is
not required and input voltages which range to ground can
easily be accommodated.
