MC33078:Low-noise op-amps

The MC33078 device is a monolithic dual 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 MC33078 device 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.
