ADV476KP66-REEL

Digital To Analog Converters Overview

The ADV476KP66-REEL is a CMOS monolithic color palette RAM-DAC designed for VGA and Personal System/2 graphics applications. It integrates a 256x18 color lookup table, pixel mask register, and triple 6-bit video D/A converters on a single chip. The device supports pipelined operation at 66 MHz, enabling simultaneous display of up to 256 colors from a total palette of 262,144 addressable colors. It features RS-343A/RS-170 compatible outputs with blanking capability on all channels and utilizes a standard MPU interface for asynchronous access to internal registers. Constructed using +5 V CMOS technology, it offers low power dissipation in a 44-pin PLCC package.
