LOW POWER DUAL OPERATIONAL AMPLIFIER LM358  
DESCRIPTION  
Outline Drawing  
The LM358 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.  
L M 358N  
Application areas include transducer amplifiers,  
DIP-8  
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 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.

Note 1 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 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.  
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: With the D358, all temperature specifications are limited to -25℃ ≤ Ta ≤ 85℃ .  
Note 5: Vo=1.4V, Rs = 0? with V + from 5V to 30V; and over the full input common-mode range (0V to  
V + -1.5V) at 25°C  
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 them 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 +  
.
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.

APPLICATION HINTS  
The LM358 is 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 0V. 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 V.  
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 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 -0.3V (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 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  
stability margin. Values of 50pF 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.  
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.
