Overview
The MC34074DR2 is a dual operational amplifier (op-amp) produced by onsemi, part of the MC33071/72/74, MC34071/72/74, and NCV33072/74A series. These op-amps are designed using quality bipolar fabrication and innovative design concepts, making them suitable for a wide range of applications. They are particularly adept for single supply operation, with a common mode input voltage range that includes ground potential. The devices feature 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, large output voltage swing, and high capacitance drive capability.
