AD8476ACPZ-R7

AD8476 is a very low power, fully differential precision amplifier with integrated gain resistors for unity gain. It is an ideal choice for driving low power, high performance ADCs as a single-ended-to-differential or differential-to-differential amplifier. It provides a precision gain of 1, common-mode level shifting, low temperature drift, and rail-to-rail outputs for maximum dynamic range. It also provides overvoltage protection from large industrial input voltages upto ±23V while operating on a dual 5V supply. Power dissipation on a single 5V supply is only 1.5mW. This device works well with SAR, Σ-Δ, and pipeline converters. The high current output stage of the part allows it to drive the switched capacitor front-end circuits of many ADCs with minimal error. It is used in applications such as ADC driver, differential instrumentation amplifier building block, single-ended-to-differential converter, battery-powered instruments.
