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.
