AD8277ARZ

产品概述

The AD8277ARZ is a general-purpose unity-gain Difference Amplifier intended for precision signal conditioning in power critical applications that require both high performance and low power. It provides exceptional common-mode rejection ratio (86dB) and high bandwidth while amplifying signals well beyond the supply rails. The on-chip resistors are laser-trimmed for excellent gain accuracy and high CMRR. It also has extremely low gain drift vs. temperature. The common-mode range of the amplifier extends to almost double the supply voltage, making these amplifiers ideal for single-supply applications that require a high common-mode voltage range. The internal resistors and ESD circuitry at the inputs also provide overvoltage protection to the op amps.
