DESCRIPTION

The

µPC4074 is a J-FET input operational amplifier. This product is designed as low noise version of the µPC4084.

The features of the

µPC4074 are more improved input equivalent noise voltage, input offset voltage and input bias

current than those of

µPC4084. By these features, the µPC4074 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.)
