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. FEATURES • Unipolar input range (0 to +10V) • 2MHz sampling rate • 4096-to-1 dynamic range (72.2dB) • Low noise, 600µVrms (1/4 of an LSB) • Outstanding differential nonlinearity error (±0.45 LSB max.) • Small, 24-pin ceramic DDIP • Low power, 1.75 Watts • Operates from ±12V or ±15V supplies • Edge-triggered, no pipeline delay • Low cost
