DESCRIPTION
The MC33078 is a monolithic dual operational
amplifier particularly well suited for audio applications. Itoffers low voltagenoise (4.5nV/√Hz ) and
high frequencyperformances (15MHz Gain Bandwidth product, 7V/µs slew rate).
In addition the MC33078 has a very low distortion
(0.002%)and excellentphase/gain margins.
The output stage allows a large output voltage
swing and symmetrical source and sink currents.
