Description

The MC33079 device is a monolithic quad

operational amplifier particularly well suited for

audio applications.

It offers low voltage noise (4.5 nV/√Hz) and high

frequency performance (15 MHz gain bandwidth

product, 7 V/µs slew rate).

In addition the MC33079 device has a very low

distortion (0.002%) and excellent phase/gain

margins.

The output stage allows a large output voltage

swing and symmetrical source and sink currents.
