DESCRIPTION
The MC33078 is a monolithic dual operational
amplifier dedicated to audio applications. The
MC33078 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 source and sink currents.
