ADV7151LS170

Digital To Analog Converters Overview

The ADV7151LS170 is a CMOS monolithic Video RAM-DAC designed for high-performance pseudo-color graphics applications. It integrates triple 10-bit D/A converters with on-chip clock control and palette RAM, supporting 8-bit pseudo-color operation at a maximum update rate of 170 MHz. The device features RS-343A/RS-170 compatible analog outputs and TTL-compatible digital inputs, enabling direct interface with standard MPU/I/O systems. Constructed in a thermally enhanced 160-lead Plastic Quad Flatpack (QFP), it provides a compact solution for professional color prepress imaging and graphics workstations requiring efficient pseudo-color rendering.
