A/D, D/C Converters for Image Signal Processing
MN6556A, MN6556AS
Low Power 8-Bit CMOS D/A Converters for Image Processing
Overview
The MN6556A and MN6556AS are 8-bit CMOS digi-
tal-to-analog converters with a maximum conversion rate
of 20 MSPS.
They use both a matrix cell and weighted current tech-
nology to achieve a low power consumption of only 50
mW. Output has an amplitude of one volt above the ground
level.
