GENERAL DESCRIPTION
The
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
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
The high current output stage of the part allows it to drive the
Rev. A
