TDA8709A
FUNCTIONAL DESCRIPTION
TDA8709A is an 8-bit ADC with internal clamping and a
preamplifier with adjustable gain.
The clamping value is switched via pin 27 between
digital 16 (for R, G, B signals) and digital 128 (for
chrominance or colour difference signals). While clamping
pulse at pin 27 is logic 1, the device will adjust the
clamping level to the chosen value. The output format can
be selected between binary and two's complement at
pin 28.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
