Low Power, Low Noise
Operational Amplifiers
The MC33178/9 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 device family incorporates the use of high
frequency PNP input transistors to produce amplifiers exhibiting low
input offset voltage, noise and distortion. In addition, the amplifier
provides high output current drive capability while consuming only
420
mA of drain current per amplifier. The NPN output stage used,
exhibits no deadband crossover distortion, large output voltage swing,
excellent phase and gain margins, low openloop high frequency
output impedance, symmetrical source and sink AC frequency
performance.
The MC33178/9 family offers both dual and quad amplifier
versions, and is available in DIP and SOIC packages.
