ADV7151LS135

Digital To Analog Converters Overview

The ADV7151LS135 is a CMOS monolithic Video RAM-DAC designed for high-performance color graphics workstations. It integrates triple 10-bit D/A converters with gamma correction, supporting 24-bit true-color operation at up to 220 MHz. The device features on-chip clock control, a 256-entry color palette RAM, and programmable pixel ports for 24-bit, 15-bit, or 8-bit pseudo-color modes. It provides RS-343A/RS-170 compatible analog outputs and TTL-compatible digital inputs via a standard MPU interface.
