LM124, LM224, LM324

Low power quad operational amplifiers

Features

■ Wide gain bandwidth: 1.3 MHz

■ Input common-mode voltage range includes

ground

■ Large voltage gain: 100 dB

■ Very low supply current per amplifier: 375 µA

■ Low input bias current: 20 nA

■ Low input offset voltage: 5 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

The LM124, LM224 and LM324 consist of four

independent, high gain, internally frequency-

compensated operational amplifiers. 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.
