ADV7150LS220

Digital To Analog Converters Overview

The ADV7150LS220 is a CMOS monolithic Video RAM-DAC designed for high-performance color graphics workstations. It integrates triple 10-bit gamma-correcting D/A converters and on-chip clock control to support 24-bit direct True-Color operation at a maximum screen update rate of 220 MHz. The device implements 30-bit True Color in 24-bit frame buffer designs and supports 15-bit True Color and 8-bit Pseudo or Indexed Color modes. Key internal components include triple 256x310 color palette RAM, programmable pixel ports, and RS-343A/RS-170 compatible analog outputs.
