Overview
The OP113FSZ is a low noise, low drift single-supply operational amplifier produced by Analog Devices Inc. This device is part of the OPx13 family, which is designed to operate from single supplies ranging from 4 V to 36 V, maintaining its low noise and precision performance across this range. The OP113FSZ is particularly suited for systems that require internal calibration, as it offers superior analog performance combined with digital correction capabilities. It is unity gain stable, has no phase reversal, and features a wide bandwidth of 3.4 MHz and a low noise density of 4.7 nV/√Hz at 1 kHz.
