A/D, D/C Converters for Image Signal Processing
MN6570F, MN6570TF, and MN6570EF
Low Power 8-Bit, 3-Channel CMOS D/A Converters for Image Processing
Overview
The MN6570F, MN6570TF, and MN6570EF are high-
speed 8-bit, 3-channel CMOS digital-to-analog convert-
ers with maximum conversion rates of 35 MSPS, 40
MSPS, and 40 MSPS, respectively.
They use both a matrix cell and weighted current tech-
nology.
The three channels use separate clock signals, so they
may be used as totally independent D/A converters.
