Description

The AD8276 / AD8277 are general-purpose, unity-gain difference amplifiers intended for precision signal conditioning in power critical applications that require both high performance and low
power. They provide exceptional common-mode rejection ratio(86 dB) 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. They also have extremely low gain drift vs. temperature.
The common-mode range of the amplifiers 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.
