LM124 (正在供货) 四路运算放大器



These devices consist of four independent high-gain frequency-compensated operational amplifiers that are designed specifically to operate from a single supply or split supply over a wide range of voltages.


  • 2-kV ESD Protection for:
    • LM224K, LM224KA
    • LM324K, LM324KA
    • LM2902K, LM2902KV, LM2902KAV
  • Wide Supply Ranges
    • Single Supply: 3 V to 32 V
      (26 V for LM2902)
    • Dual Supplies: ±1.5 V to ±16 V
      (±13 V for LM2902)
  • Low Supply-Current Drain Independent of
    Supply Voltage: 0.8 mA Typical
  • Common-Mode Input Voltage Range Includes
    Ground, Allowing Direct Sensing Near Ground
  • Low Input Bias and Offset Parameters
    • Input Offset Voltage: 3 mV Typical
      A Versions: 2 mV Typical
    • Input Offset Current: 2 nA Typical
    • Input Bias Current: 20 nA Typical
      A Versions: 15 nA Typical
