The MC33078 offers low voltage noise (4.5nV/ Hz ) and high frequency performances (15MHz gain bandwidth product, 7V/s slew rate). In addition the MC33078 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.
