Function : G = 0.2, Level Translation,16-Bit ADC Driver
Maker : Analog Devices
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 applic ations 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-to-rail outputs make it an easy to use building block. Single-supply operation reduces the power consumption of the amplifier and helps to protect the ADC from overdrive conditions. Internal, matched, precision laser-trimmed resistors ensure low gain error, low gain drift of 1 ppm/°C (maximum), and high common-mode rejection of 80 dB. Low offset and low offset drift, combined with its fast settling time, make the AD8275 suitable for a variety of data acquisition applications where accurate and quick capture is required.
