Overview
The AD626AR from Analog Devices Inc. is a low-cost, single-supply differential amplifier designed for amplifying and low-pass filtering small differential voltages from sources with large common-mode voltages. This amplifier is suitable for a variety of applications, including current sensing, pressure transducers, position indicators, and strain gages. The AD626AR can operate from either a single supply of +2.4 V to +12 V or dual supplies of ±1.2 V to ±6 V, making it versatile for different system requirements. It features a high common-mode rejection ratio (CMRR) of 90 dB and includes input protection against continuous overloads up to 50 V, as well as RFI filters in the attenuator network.
