A/D, D/C Converters for Image Signal Processing
MN65702H
Low Power 8-Bit, 3-Channel CMOS D/A Converter for Image Processing
Overview
The MN65702H is a high-speed 8-bit, 3-channel CMOS
digital-to-analog converter. (Two channels use serial in-
put.)
It uses both a matrix cell and weighted current technol-
ogy to achieve both low power consumption and high
speed.
It features built-in output resistor, reference resistor, and
low pass filter, and provides independent output ampli-
tude adjustment for the Y (luminance) and C (chroma)
synchronization signals. The Y (luminance signal) can
be superimposed with an external SYNC signal.
