LM224A, LM324A

Low-power quad operational amplifiers

Datasheet - production data

Features

• Wide gain bandwidth: 1.3 MHz

• Input common mode voltage range includes

ground

• Large voltage gain: 100 dB

• Very low supply current/amplifier: 375 µA

• Low input bias current: 20 nA

• Low input offset voltage: 3 mV max.

• Low input offset current: 2 nA

• Wide power supply range:

– Single supply: +3 V to +30 V

– Dual supplies: ±1.5 V to ±15 V

Description

These circuits consist of four independent, high

gain operational amplifiers with frequency

compensation implemented internally. They

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.
