The TDA8786; TDA8786A is a 10-bit analog-to-digital interface for CCD cameras. The device includes a
correlated double sampling circuit, AGC, a soft clipper circuit and a low power 10-bit Analog-to-Digital Converter
(ADC) together with its reference voltage regulator.
The AGC and soft clipper circuits are controlled by on-chip DACs via a serial interface.
A 10-bit DAC controls the ADC input clamp level.
A pre-blanking function is also included.
An additional DAC is provided for additional system controls; its output voltage range is 1.4 V (p-p) which is
available at pin OFDOUT.
