GENERAL DESCRIPTION

The functionally complete, easy-to-use ADS-CCD1202 is a 12-bit, 2MHz Sampling A/D Converter whose performance and production testing have been optimized for use in CCD applications. This device delivers the lowest noise (600µVrms) and the best differential linearity error (±0.45LSB maximum) of any commercially available 12-bit A/D in its speed class. It can respond to full scale input steps (from empty to full well) with less than a single count of error, and its input is immune to overvoltages that may occur due to blooming.
