GENERAL DESCRIPTION
The TDA8787A is a 10-bit analog-to-digital interface for
CCD cameras. The device includes a correlated double
sampling circuit, a PGA, clamp loops and a low-power
10-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 peak-to-peak
which is available at pin OFDOUT.
