Overview
The MC34072PG, produced by onsemi, is a high-performance operational amplifier (op-amp) that belongs to the MC33071/72/74, MC34071/72/74, NCV33072/74A series. This device is fabricated using quality bipolar technology with innovative design concepts, making it suitable for a wide range of applications. The MC34072PG is particularly noted for its single supply operation, with a voltage range of 3.0 V to 44 V, and its ability to operate from split supplies as well. It features a Darlington input stage, which provides high input resistance, low input offset voltage, and high gain. The all NPN output stage ensures no deadband crossover distortion and offers a large output voltage swing, high capacitance drive capability, and excellent phase and gain margins.
