MN6570EF

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 highspeed 8-bit, 3-channel CMOS digital-to-analog converters with maximum conversion rates of 35 MSPS, 40 MSPS, and 40 MSPS, respectively. They use both a matrix cell and weighted current technology. The three channels use separate clock signals, so they may be used as totally independent D/A converters.
