AD8476BRMZ

产品概述

The AD8476BRMZ 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. The AD8476 also provides overvoltage protection from large industrial input voltages up to ±23V while operating on a dual 5V supply. Power dissipation on a single 5V supply is only 1.5mW. The AD8476 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. Considering its low power consumption and high precision, the slew-enhanced AD8476 has excellent speed, settling to 16-bit precision for 250kSPS acquisition times.
