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
