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.

1. Either or both input voltages must not exceed the magnitude of VCC+ or VCC- .
2. Short-circuits can cause excessive heating and destructive dissipation.
3. Rth are typical values.
4. Human body model: A 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating.
5. Machine model: A 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of connected pin combinations while the other pins are floating.
6. Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly to the ground through only one pin. This is done for all pins.
