Description
The MC33078 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 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.
