Product Introduction

Overview

The OP293FS-REEL7, produced by Analog Devices Inc., is a precision, micropower operational amplifier. It belongs to the OP293 family, which is known for its high precision, low supply current, and the ability to operate at low voltages. These amplifiers are designed for single-supply operation and can function with supply voltages as low as +1.7 V or ±0.85 V, making them ideal for battery-powered equipment and other low-voltage applications.
