ADV7152LS220

Digital To Analog Converters Overview

The ADV7152LS220 is a CMOS monolithic Video RAM-DAC featuring three 10-bit digital-to-analog converters with a 220 MHz bandwidth. It supports true-color graphics operation at maximum screen update rates, implementing 30-bit color depth within 24-bit frame buffer designs. The device integrates triple 256-entry 10-bit (or 256-entry 30-bit) color palette RAMs, on-chip clock control circuits, and programmable pixel port multiplexers. It provides RS-343A/RS-170 compatible analog outputs and TTL-compatible digital inputs via a standard MPU interface.

Digital To Analog Converters Feature Summary

• Triple 10-bit video DACs with 220 MHz bandwidth and gamma correction capabilities
• Integrated 256 x 10-bit (or 256 x 30-bit) color palette RAM with priority select registers
• Programmable pixel port supporting 24-bit and 8-bit pseudo pixel data serialization
• On-chip clock generator/divider circuit for synchronized pixel input processing

Digital To Analog Converters Applications

• High resolution, true color graphics workstations
• Professional color prepress imaging systems

Digital To Analog Converters Procurement Notes

Verify the specific suffix LS220 against official Analog Devices documentation to confirm package type, temperature range, and lead finish specifications. Ensure compatibility with existing system voltage requirements and thermal management solutions, as the device utilizes a thermally enhanced 100-lead plastic quad flatpack (QFP).

Digital To Analog Converters Selection Notes

Select this component for applications requiring direct true-color operation without external look-up tables. Consider the 100-lead QFP package constraints and thermal dissipation needs, as the device is thermally enhanced to achieve a junction-to-case thermal resistance of less than 1.0 C/W. Verify interface compatibility with the host processor's parallel data structure.

Digital To Analog Converters Part Context

The ADV7152 series represents a class of complete analog output Video RAM-DACs designed for high-performance color graphics. This specific model integrates graphic functions onto a single CMOS chip, allowing for efficient implementation of 24-bit direct true-color operation and supporting various color modes including 15-bit true color and 8-bit pseudo color.

Digital To Analog Converters Replacement Considerations

Consult Analog Devices documentation for verified cross-reference part numbers. Substitutions must match the 100-lead QFP package, 220 MHz bandwidth, and integrated palette RAM architecture.
