DESCRIPTION

The MC33078 isamonolithic dualoperational 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 MC33078 has a very low distortion
(0.002%) and excellent phase/gain margins.

The output stage allows a large output voltage
swing and symmetrical sourceand sink currents.
