Description

This is 16-Bit ADC Driver. FEATURES Translates ±10 V to +4 V Drives 16-bit SAR ADCs Small MSOP package Input overvoltage: +40 V to 35 V (VS = 5 V) Fast settling time: 450 ns to 0.001% Rail-to-rail output Wide supply operation: +3.3 V to +15 V High CMRR: 80 dB Low gain drift: 1 ppm, °C Low offset drift: 2.5 μV, °C APPLICATIONS Level translator ADC driver Instrumentation amplifier building block Automated test equipment 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. The AD8275 has fast settling time of 450 ns and low distortion, making it suitable for driving medium speed successive approximation (SAR) ADCs. Its wide input voltage range and rail-torail outputs make it an easy to use building block. Singl.
