Overview
The OP293ESZ-REEL, produced by Analog Devices Inc., is a single-supply operational amplifier that combines high precision, low supply current, and the ability to operate at low voltages. This amplifier is part of the OP293 series, which is designed for high performance in single-supply systems. The OP293 can operate from a supply voltage as low as +1.7 V or ±0.85 V, making it suitable for battery-powered equipment and other low-voltage applications.
