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.

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.
