Overview
The MC33178PG is part of the MC33178/9 series, a family of high-quality monolithic operational amplifiers (op-amps) from ON Semiconductor. These op-amps employ Bipolar technology and are designed for quality audio and data signal processing applications. They utilize high-frequency PNP input transistors, resulting in low input offset voltage, noise, and distortion. The amplifiers offer high output current drive capability with a low drain current of 420µA per amplifier. The NPN output stage ensures no deadband crossover distortion, large output voltage swing, and excellent phase and gain margins.
The MC33178PG is available in both dual and quad amplifier versions and is tested over the vehicular temperature range. It is offered in various package types, including DIP and SOIC.
