Overview
The AD8274ARMZ, produced by Analog Devices Inc., is a high-performance difference amplifier designed to deliver excellent AC and DC performance. Built on Analog Devices' proprietary iPolar® process and utilizing laser-trimmed resistors, the AD8274 achieves low distortion, high gain accuracy, and excellent common-mode rejection ratio (CMRR). This amplifier is well-suited for applications requiring precise signal amplification and is particularly useful in measuring large industrial signals due to its ability to handle supply voltages up to ±18 V (+36 V single supply).
