The AD8279ARZ is a general-purpose Difference Amplifier intended for precision signal conditioning in power critical applications that require both high performance and low power. The AD8279 provides exceptional common-mode rejection ratio (80dB) and high bandwidth while amplifying input signals that are 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 triple the supply voltage (for G = 1/2), making the amplifier 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 amp.
