LM358
LOW POWER DUAL OPERATIONAL AMPLIFIERS
Description
Pin Assignments
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.

SOP-8L
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.
Applications
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 Compliant (Note 1)
Eliminates the need for dual supplies
Compatible with all forms of logic
Two internally compensated op amps
Low power drain ideal for battery operation
Allows direct sensing near GND
VOUT 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.
