Overview
The AD8223ARZ-RL, produced by Analog Devices Inc., is an integrated single-supply instrumentation amplifier designed to deliver high performance and versatility. This amplifier is optimized for operation on a single supply voltage ranging from 3 V to 24 V, but it also performs well with dual supply voltages from ±2 V to ±12 V. The AD8223ARZ-RL features a rail-to-rail output swing, which maximizes the dynamic range, especially in low supply voltage conditions. It is known for its low power consumption, wide input common-mode range, and the ability to amplify signals with a common-mode voltage up to 150 mV below ground.
