Short for Random Access Memory Digital-to-Analog Converter,
a single chip
on video adapter
cards. The RAMDAC’s role is to convert digitally encoded images into analog signals that can be displayed by a monitor
. A RAMDAC actually consists of four different components – SRAM
to store the color map and three digital-to-analog converters (DACs)
, one for each of the monitor’s red, green, and blue electron guns.
