Dual/Quad Low Noise
Operational Amplifiers
The MC33078/9 series is a family of high quality monolithic amplifiers
employing Bipolar technology with innovative high performance concepts for
quality audio and data signal processing applications. This family
incorporates the use of high frequency PNP input transistors to produce
amplifiers exhibiting low input voltage noise with high gain bandwidth
product and slew rate. The all NPN output stage exhibits no deadband
crossover distortion, large output voltage swing, excellent phase and gain
margins, low open loop high frequency output impedance and symmetrical
source and sink AC frequency performance.
The MC33078/9 family offers both dual and quad amplifier versions,
tested over the automotive temperature range and available in the plastic
DIP and SOIC packages (P and D suffixes).
