Overview
The ADA4523-1BCPZ-RL7, produced by Analog Devices Inc., is a high-voltage, low-noise, zero-drift operational amplifier designed to deliver precision DC performance over a broad supply range of 4.5 V to 36 V. This op amp is notable for its low offset voltage, minimal offset voltage drift, and high immunity to electromagnetic interference (EMI). It features self-calibrating circuitry that ensures low offset voltage drift with temperature and zero drift over time, making it ideal for high dynamic range test, measurement, and instrumentation systems.
