Overview
The OP113ESZ-REEL, produced by Analog Devices Inc., is part of the OPx13 family of low noise, low drift single-supply operational amplifiers. These amplifiers are designed to operate from single supplies ranging from 4 V to 36 V, maintaining their low noise and precision performance across this range. The OP113 is unity gain stable, with a typical gain bandwidth product of 3.4 MHz and a slew rate exceeding 1 V/μs. This makes it suitable for a variety of applications requiring high precision and low noise.
