GENERAL DESCRIPTION
The IT6902 is a triple high speed,
digital-to-analog converter on a single
monolithic chip. There are three high
speed, 10-bit, video D/A converters
with complementary outputs, a
standard TTL input interface, and a
high impedance, analog output
current source.
3.3V /1.8V power supply and clock
are all required to make the part
functional. The IT6902 also has a
Power-Down Mode.
The IT6902 is fabricated in a 1.8V
CMOS process and available in a
64-lead LQFP package.
