En RAMDAC (Random Access Memory Digital-to-Analog Converter) isch en Chip uf dr Grafikcharte, wo für d Umwandlig vo digitale in analogi Bildsignal zueständig isch. Er wird hauptsächlich für di analoge Usgabe verwendet, zum Bispiel bi Monitore, wo über VGA agschlosse sind.
Dr RAMDAC bestoot us eme chline statische Speicher (RAM), wo d Farbtabelle (LUT – Look-Up Table) enthaltet, und us drü D/A-Wandler – je eine für d Grundfarbe Rot, Grüen und Blau. Jede Wandler setzt de digitali Farbwärt in en analogi Spannig um, wo denn zäme s analoge Videosignal ergä.
