AD8276ARZ (ANALOG DEVICES)

The AD8276ARZ is a Wide supply Range 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. The common-mode range extends to almost double the supply voltage 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. While the amplifier is optimized for use as difference amplifier, it can also be connected in high precision, single-ended configurations with G = -1, +1, +2. The AD8276 provides an integrated precision solution that has smaller size and better performance than a discrete alternative.
