Overview
The OP293FS-REEL, manufactured by Analog Devices Inc., is a precision, micropower operational amplifier. This component is part of the OP193/OP293 family, known 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. This makes it particularly useful for battery-powered equipment and other low-voltage applications.
