FEATURES

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.

Packaged in an industry-standard, 24-pin, ceramic DDIP, the

ADS-CCD1202 requires ±15V (or ±12V) and +5V supplies and

typically consumes 1.75 (1.45) Watts. The device is 100%

production tested for all critical performance parameters and is

fully specified over both the 0 to +70°C and –55 to +125°C

operating temperature ranges.

For those applications using correlated double sampling, the

ADS-CCD1202 can be supplied without its internal sample-

hold amplifier and achieve conversion rates up to 2.5MHz.
