Overview
The AD623BRZ-RL, produced by Analog Devices Inc., is an integrated, single- or dual-supply instrumentation amplifier. It is designed to deliver rail-to-rail output swing using supply voltages from 2.7 V to 12 V. This amplifier offers high accuracy DC performance, low power consumption, and user flexibility through single gain set resistor programming. The AD623BRZ-RL conforms to the 8-lead industry standard pinout configuration and is available in an 8-lead SOIC package.
