RAMDAC - 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.
