DESCRIPTION
The MC33079 is a monolithic quad operational
amplifier particularly well suited for audio applications. It offers low voltage noise (4.5nV/√

Hz ) and
high frequency performances (15MHz Gain Bandwidth product, 7V/µs slew rate).
In addition the MC33079 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.
