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 (500

μA); 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

•

SOP-8L packaging

•

“Green” Molding Compound (No Br, Sb)

•

Lead Free Finish/ RoHS Compliant (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 battery operation

•

Allows direct sensing near 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.
