GENERAL DESCRIPTION

The TDA9962 is a 12-bit analog-to-digital interface for

CCD cameras. The device includes a correlated double

sampling circuit, PGA, clamp loops and a low-power 12-bit

ADC together with its reference voltage regulator.

The PGA gain and the ADC input clamp level are

controlled via the serial interface.

An additional DAC is provided for additional system

controls; its output voltage range is 1.0 V (p-p) which is

available at pin OFDOUT.
