DESCRIPTION

The

μ PC4572 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.

FEATURES

• 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
