AD8275 G = 0.2, Level Translation, 16-Bit ADC Driver

Level Translator ADC Driver Automated test equipment Instrumentation Amplifier Building Block

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

The AD8275 has fast settle time and low distortion making it suitable for driving fast, 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.

The AD8275 can be used as an analog front end, or it can follow buffers to level translate high voltages to a voltage range accepted by the ADC. In addition, the AD8275 can be configured for diff-erential outputs if used with a differential ADC. The AD8275 is available in a space-saving, 8-lead MSOP and is specified for performance over the −40°C to +85°C temperature range.
