DESCRIPTION

The

μ PC4072 is a J-FET input operational amplifier. This product is designed as low noise version of the μ PC4082.

The features of the

μ PC4072 are more improved input equivalent noise voltage, input offset voltage and input bias

current than those of

μ PC4082. By these features, the μ PC4072 is excellent choice for wide variety of applications

including audio preamplifier and active filter.

FEATURES

• Low noise: en = 17 nV/ Hz (TYP.)

• Very low input bias and offset currents

• Output short circuit protection

• High input impedance...J-FET Input stage

• Internal frequency compensation

• High slew rate...13 V/

μs (TYP.)
