T he ADV473 is a complete analog output, Video RAM-DAC
on a single CMOS monolithic chip. T he part is specifically
designed for true-color computer graphics systems.
T he ADV473 integrates a number of graphic functions onto one
device allowing 24-bit direct true-color operation at the maxi-
mum screen update rate of 135 MHz. It can also be used in
other modes, including 15-bit true color and 8-bit pseudo or in-
dexed color. T he ADV473 is fully PS/2 and VGA register level
compatible. It is also capable of implementing IBM’s X GA
standard.
