ADV476KP40 is listed in the Digital To Analog Converters range at ChipApex. The manufacturer field lists Analog Devices Inc.. Its product description is IC DAC 6BIT A-OUT 44PLCC. Review the specifications below when checking this part for your BOM.
The ADV476KP40 is a CMOS monolithic color palette RAM-DAC designed for VGA and Personal System/2 graphics applications. It integrates a 256x18-bit color lookup table, pixel mask register, and triple 6-bit video D/A converters on a single chip. The device supports pipelined operation at up to 40 MHz, enabling simultaneous display of 256 colors from a 262,144-color palette. It features RS-343A/RS-170 compatible outputs and standard MPU interface for asynchronous access to internal registers. Constructed with +5V CMOS technology, it offers low power dissipation in a 28-pin DIP package.
The ADV476KP40 belongs to the ADV476 family of RAM-DACs manufactured by Analog Devices. The 'KP' suffix indicates a plastic DIP package variant, while '40' specifies the speed grade supporting 40 MHz operation. This component serves as a pin-compatible and software-compatible replacement for legacy components like the INMOS 171/176, maintaining compatibility with standard VGA timing and signaling protocols.
