Overview
The NCV33172DR2G is a dual operational amplifier from onsemi, part of the MC33171/72/74 series. These devices are designed using quality bipolar fabrication and innovative design concepts, making them suitable for a wide range of applications. They operate at a low supply current of 180 µA per amplifier and offer a gain bandwidth product of 1.8 MHz and a slew rate of 2.1 V/µs, all without the use of JFET device technology. The amplifiers are particularly suited for single supply operation, with the common mode input voltage including ground potential (VEE), and they can also be operated from split supplies. 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 large output voltage swing.
