Overview
The OP193FSZ-REEL7 is a precision, micropower operational amplifier produced by Analog Devices Inc. This single-supply operational amplifier is renowned for its high precision, low supply current, and the ability to operate at low voltages. It is designed for high performance in single-supply systems, with input and output ranges that include ground, and outputs that swing from the negative rail to within 600 mV of the positive supply. The combination of high accuracy and low power operation makes the OP193FSZ-REEL7 particularly useful for battery-powered equipment.
