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.)
