A/D, D/C Converters for Image Signal Processing
MN65702H
Low Power 8-Bit, 3-Channel CMOS D/A Converter for Image Processing
Pin Assignment Overview
The MN65702H is a high-speed 8-bit, 3-channel CMOS
digital-to-analog converter. (Two channels use serial input.)
It uses both a matrix cell and weighted current technology 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 amplitude adjustment for the Y (luminance) and C (chroma)
synchronization signals. The Y (luminance signal) can
be superimposed with an external SYNC signal.
Features
Maximum conversion rate: 20 MSPS (min.)
Linearity error: ±0.2 LSB (typ.)
Differential linearity error: ±0.2 LSB (typ.)
Power supply voltage: VDD= 3.3 ±0.3 V , VCC= 4.8
±0.3 V
Full scale current: 2.33 mA (typ.)
Power consumption: 100 mW (typ.) (f
