G = 0.2, Level Translation, 16-Bit ADC Driver
GENERAL DESCRIPTION
The AD8275 is a G = 0.2 difference amplifier that can be used to translate ±10 V signals to a +4 V level. It solves the problem typically encountered in industrial and instrumentation applications where ±10 V signals must be interfaced to a single-supply 4 V or 5 V ADC. The AD8275 interfaces the two signal levels, simplifying design.
