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. The AD8276/AD8277 are unity-gain stable. While they are
optimized for use as difference amplifiers, they can also be connected in high precision, single-ended configurations with G = ?1, +1, +2. The AD8276/AD8277 provide an integrated precision solution that has smaller size, lower cost, and better
performance than a discrete alternative. The AD8276/AD8277 operate on single supplies (2.0 V to 36 V)
or dual supplies (±2 V to ±18 V). The maximum quiescent
supply current is 200 μA per channel, which is ideal for battery-
operated and portable systems.
