Overview
The MC34072DR2, produced by onsemi, is part of the MC33071/72/74, MC34071/72/74, NCV33072/74A series of monolithic operational amplifiers. These op-amps are designed with quality bipolar fabrication and innovative design concepts, offering superior performance characteristics. They are particularly suited for single supply operation, with a common mode input voltage range that includes ground potential (VEE). The Darlington input stage provides high input resistance, low input offset voltage, and high gain. The all NPN output stage ensures no deadband crossover distortion, large output voltage swing, high capacitance drive capability, and excellent phase and gain margins.
