Description

The LM124, LM224W and LM324x 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.

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 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
