GENERAL DESCRIPTION
The TDA8783 is a 10-bit analog-to-digital interface for
CCD cameras. The device includes a correlated double
sampling circuit, AGC and a low-power 10-bit
Analog-to-Digital Converter (ADC) together with its
reference voltage regulator.
The AGC and CDS have a bandwidth circuit controlled by
on-chip DACs via a serial interface.
A 10-bit DAC controls the ADC input clamp level.
An additional 8-bit DAC is provided for additional system
controls; its output voltage range is 1.4 V (p-p) which is
available at pin OFDOUT.
