DESCRIPTION
The MC33078 is a monolithic dual operational
amplifier particularly well suited for audio applica-
tions. It offers low voltage noise (4.5nV/√Hz ) and
high frequencyperformances (15MHz Gain Band-
width product, 7V/µs slew rate).
In additionthe MC33078has a verylow distortion
(0.002%)and excellentphase/gain margins.
The output stage allows a large output voltage
swing and symmetrical source and sink currents.
