Description
The MC33079 is a monolithic quad operational
amplifier particularly well suited for audio
applications.
It offers low voltage noise (4.5 nV/√Hz) and high
frequency performance (15 MHz gain bandwidth
product, 7 V/µs slew rate).
In addition the MC33079 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.
