GENERAL DESCRIPTION
The TDA8709A is an analog input interface for video signal
processing. It includes a an input selector
(one out-of-three video signals), video amplifier with clamp
and external gain control, an 8-bit analog-to-digital
converter (ADC) with a sampling rate of 32 MHz and an
input selector.
