MC33079 Low noise quad operational amplifier Features ■ Low voltage noise: 4.5 nV/√Hz ■ High gain bandwidth product: 15 MHz ■ High slew rate: 7 V/µs ■ Low distortion: 0.002% ■ Large output voltage swing: +14.3 V/-14.6 V ■ Excellent frequency stability ■ ESD protection 2 kV Description The MC33079 device is a monolithic quad 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 MC33079 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.

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