Description
The LM358 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 LM358 series can be directly
operated from the standard +5V power supply voltage which
is used in digital systems and will easily provide the required
interface electronics without requiring an additional ±15V
power supply.
Features
• Internally frequency compensated for unity gain
• Large dc voltage gain: 100 dB
• Very low supply current drain (500μA); essentially
independent of supply voltage
• Wide bandwidth (unity gain): 1MHz (temperature
compensated)
• Input common-mode voltage range includes ground
• Differential input voltage range equal to the power supply
voltage
• Low input offset voltage: 2mV
• Wide power supply range:
o Single supply: 3V to 32V
o Dual supplies: ±1.5V to ±16V
• Large output voltage swing: 0V to V+ - 1.5V
• SOP-8L packaging
• “Green” Molding Compound (No Br, Sb)
• Lead Free Finish/ RoHS Com pliant (Note 1)
Pin Assignments
Applications
• Eliminates the need for dual supplies
• Compatible with all forms of logic
• Two internally compensated op amps
• Low power drain ideal for batt ery operation
• Allows direct sensing near GND
• V
OUT can swing to GND
Unique Characteristics
• In the linear mode the input common-mode voltage
range includes ground and the output voltage can
also swing to ground, whilst operating from only a
single power supply voltage.
• The unity gain crossing frequency is temperature
compensated.
• The input bias current is temperature compensated.

TOP Operating Temperature Range 0 to +70 oC
TST Storage Temperature Range -65 to +150 oC
Notes: 2. For operating at high temperatures, the LM358 must be derated based on a +125°C maximum junct i on temperature and a
thermal resistance of 189°C/W, which applies for the device soldered in a printed circuit board, operating in a still air ambient. The dissipation is
the total of both amplif iers; use external resistors, where possible, to allow the amplifier to saturate or to reduce the power which is dissipated in
the integrated circuit.
3. Short circuits from the output to V+ can cause excessive heating and eventual destruction. When considering short circuits to ground, the
maximum output current is approximately 40mA 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.
4. 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 junc tion of the in put
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 le vel (or to
ground for a large overdrive) for the time duration that an input is driven negative. This is not des truct ive 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).

output so no loading change exists on the input lines.
8. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V (at25°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, independent of the magnitude of V+.
9. 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.
10.Short circu its from the output to V+ can cause excessive heating and eventual destruction. When considering short circuits to ground, the output
maximum current is approximately 40mA 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.

Application Information
The LM358 series are op amps operate with only a sin gle
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 vo ltage 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 resulting 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
accommodated and, as input differential voltage
protection diodes are not nee ded, no large input currents
result. 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 f or 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 transistors 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 stabilit y marg in. Values of
50pF can be accommodated using the worst-case non-
inverting unity gain connection. Large closed loop gains
or resistive isolation should be used if a larger load
capacitance must be driven by the am plifier.
The bias network of the LM358 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 destroyed, 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 excessive 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 protected 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 emphas ize operation on only a single po we r
supply voltage. If complementary power supplies are
available, all of the standard op amp circuits can be
used. In general, introducing 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.
