Description
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.
