Overview
The MC33172DR2G is a single supply, low power, dual operational amplifier produced by onsemi. This device is part of the MC33171/72/74 series, which employs quality bipolar fabrication and innovative design concepts. These operational amplifiers operate at 180 µA per amplifier, offering a gain bandwidth product of 1.8 MHz and a slew rate of 2.1 V/µs without the use of JFET device technology. They are particularly suited for single supply operation, as the common mode input voltage includes ground potential (VEE). The Darlington input stage provides high input resistance, low input offset voltage, and high gain, while the all NPN output stage ensures no deadband crossover distortion and a large output voltage swing.
