T he ADV478 (ADV) and ADV471 are pin compatible and
software compatible RAM-DACs designed specifically for
Personal System/2 compatible color graphics.
T he ADV478 has a 256
×
24 color lookup table with triple 8-bit
video D/A converters. It may be configured for either 6 bits or
8 bits per color operation. T he ADV471 has a 256
×
18 color
lookup table with triple 6-bit video D/A converters.
Options on both parts include a programmable pedestal (0 or
7.5 IRE) and use of an external voltage or current reference.

Fifteen overlay registers provide for overlaying cursors, grids,
menus, EGA emulation, etc. Also supported is a pixel read
mask register and sync generation on all three channels.
T he ADV478 and ADV471 generate RS-343A compatible
video signals into a doubly terminated 75
load, and RS-170
compatible video signals into a singly terminated 75
load,
without requiring external buffering. Differential and integral
linearity errors are guaranteed to be a maximum of
±
1 LSB for
the ADV478 and
±
1/4 LSB for the ADV471 over the full tem-
perature range.
