GENERAL DESCRIPTION  
The AD8275 is a G = 0.2 difference amplifier that can be used  
to translate ±±0 V signals to a +4 V level. It solves the problem  
typically encountered in industrial and instrumentation applic-  
ations where ±±0 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 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.  
The AD8275 has fast settling time of 450 ns and low distortion,  
making it suitable for driving medium speed successive approx-  
imation (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 ± 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.
