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.
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 mW.
The
AD8476
works well with SAR, Σ-Δ, and pipeline converters.
The high current output stage of the part allows it to drive the
Rev. A

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.
