MP8831AS Datasheet PDF - Exar Corporation

GENERAL DESCRIPTION
The MP8831 is a 1.67MSPS image digitizing chip that includes a 10-bit A/D Converter with digitally controlled references. This allows imaging systems to calibrate for individual pixel offset and gain errors. The offset can be adjusted from 0.175V to 0.345V in 64 steps (6 bit resolution), while the full scale range (i.e. peak to peak input range) is adjustable up to 2.82V in 1024 steps (10 bit resolution).
