BIPOLAR ANALOG INTEGRATED CIRCUIT
μ PC4572
LOW SUPPLY VOLTAGE, ULTRA LOW-NOISE, HIGH SPEED, WIDE BAND,
LOW IB DUAL OPERATIONAL AMPLIFIER
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.
