ADV7151LS220

Digital To Analog Converters Overview

The ADV7151LS220 is a CMOS triple 10-bit video RAM-DAC designed for high-performance color graphics workstations. It integrates three 220 MHz D/A converters with on-chip gamma correction and a 256-color palette RAM, enabling 24-bit true-color operation at maximum screen update rates. The device supports multiple pixel data formats including 24-bit, 15-bit, and 8-bit pseudo-color modes via programmable serializers. It features TTL-compatible digital inputs, standard MPU I/O interfaces, and RS-343A/RS-170 compatible analog outputs, facilitating direct integration into professional imaging systems.
