Sales Briefcase
  • The LM124, LM224x 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.

    Key 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
