GENERAL DESCRIPTION  
The 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.  
switched capacitor front-end circuits of many ADCs with  
minimal error.  
Unlike many differential drivers on the market, the AD8476 is  
a high precision amplifier. With 200 µV maximum output  
offset, 39 nV/√Hz noise, and −102 dB THD + N at 10 kHz, the  
AD8476 pairs well with low power, high accuracy converters.  
Considering its low power consumption and high precision, the  
slew-enhanced AD8476 has excellent speed, settling to 16-bit  
precision for 250 kSPS acquisition times.  
The AD8476 also provides overvoltage protection from large  
industrial input voltages up to 23 V while operating on a dual 5 V  
supply. Power dissipation on a single 5 V supply is only 1.5 m W.  
The AD8476 is available in space-saving 16-lead, 3 mm × 3 mm  
LFCSP and 8-lead MSOP packages. It is fully specified over the  
−40°C to +125°C temperature range.  
The AD8476 works well with SAR, Σ-Δ, and pipeline converters.  
The high current output stage of the part allows it to drive the
