Panasonic MN6570F, MN6570TF, MN6570EF Datasheet

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.
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.)
