DESCRIPTION
The MC33079 is a monolithic quad operational
amplifier particularly well suited for audio applications. It offerslow voltage noise (4.5nV/√Hz ) and
high frequencyperformances (15MHzGain Bandwidth product, 7V/µsslew rate).
In addition the MC33079has a verylow distortion
(0.002%)and excellentphase/gainmargins.
The output stage allows a large output voltage
swing andsymmetrical source and sink currents.
