Overview

Precision attenuation:G=0.4,G=0.8 Fully differential or single-ended input/output Differential output designed to drive precision ADCs Drives switched capacitor andZ-A ADCs Rail-to-rail output VOCM pin adjusts output common-mode voltage Robust overvoltage protection up to±15V(Vs=+5V) Single supply:3Vto 10V Dual supplies:±1.5Vto±5V High performance Suited for driving 18-bit converters up to 4 MSPS 10nV/VHz output noise 3 ppm/C gain drift 500 μV maximum output offset 50 V/us slew rate Low power:3.2 mA supply current

The AD8475BRMZ works extremely well with SAR,Z-A, and pipeline converters. The high current output stage of the part allows it todrive the switched capacitor front-end circuits of many ADCs with minimal error. Unlike many differential drivers in the market, the AD8475BRMZ is a high precision amplifier. With 500 uV maximum output offset, 10nV//Hz output noise, and-112 dB THD+N, the AD8475BRMZ pairs well with high accuracy converters. Considering its low power consumption and high precision, the slew-enhanced AD8475BRMZ has excellent speed, settling to 18-bit precision for 4 MSPS acquisition. The AD8475BRMZ is available in a space-saving 16-lead 3mm×3mm LFCSP package and a 10-lead MSOP package. It is fully specifed over the-40℃ to +85C temperature range.
