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 Features Maximum conversion rate: MN6570F: 35MSPS (min.) MN6570TF and MN6570EF: 40 MSPS (min.) Linearity error: ±0.2 LSB (typ.) Differential linearity error: ±0.2 LSB (typ.) Power supply voltage: VCC= 5.0±0.5 V Power consumption: MN6570F: 340 mW (typ.) MN6570TF and MN6570EF: 190 mW (typ.) Full scale current: MN6570F: 13 mA (typ.) MN6570TF and MN6570EF: 5 mA (typ.) DB5 DB6 DB7 DB8 AVSS AVSS IOB N.C. IOG N.C.

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.
