Overview
The AD623ARZ, produced by Analog Devices Inc., is an integrated instrumentation amplifier that offers high flexibility and performance. It can operate on single or dual supplies with voltages ranging from 2.7 V to 12 V, providing rail-to-rail output swing. This amplifier is designed with an 8-lead industry standard pinout configuration, allowing for easy integration into various applications. The AD623ARZ can be configured for unity gain (G = 1) without any external resistors and can be programmed for gains up to 1000 with an external gain-setting resistor.
