The μPC4572 is a dual wide band, ultra low noise operational amplifier designed for low supply voltage operation of +4 V to +14 V single supply and ±2 V to ±7 V split supplies. Using high hFE PNP transistors for the input circuit, Input bias current and input equivalent noise are better than conventional wide band operational amplifier. The μ PC4572 is an excellent choice for preamplifiers and active filters in audio, instrumentation, and communication circuit.


  • Ultra low noise: en = 4.0 nV/ √Hz
  • Low input bias current: 100 nA
  • High slew rate: 6 V/ μs
  • Low supply voltage: ±2 V to ±7 V (Split) +4 V to +14 V (Single)
  • Internal frequency compensation
