ADV7150LS135

Digital To Analog Converters Overview

The ADV7150LS135 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 135 MHz. The device features 30-bit True Color capability in 24-bit frame buffer designs, along with 15-bit True Color and 8-bit pseudo-color modes. Key electrical parameters include a +5 V supply voltage, TTL-compatible digital inputs, and RS-343A/RS-170 compatible analog outputs.

Digital To Analog Converters Feature Summary

• Triple 10-bit gamma-correcting D/A converters supporting 24-bit (30-bit gamma corrected) True Color operation
• On-chip clock control circuit and programmable pixel port for 24-bit, 15-bit, and 8-bit data
• Triple 256 x 310 (256 x 330) color palette RAM with priority select registers
• TTL-compatible digital inputs and standard MPU I/O interface

Digital To Analog Converters Applications

• High resolution, True Color graphics workstations
• Professional color prepress imaging systems
• Video RAM-DAC implementations requiring 24-bit direct True Color at 135 MHz

Digital To Analog Converters Part Context

The ADV7150LS135 belongs to the ADV7150 family of Video RAM-DACs from Analog Devices. The 'LS' suffix typically denotes a specific speed grade or package variant within this series, while '135' indicates the maximum operating frequency of 135 MHz. This component is part of a line that also includes variants like the ADV7150 and ADV7151, differentiated by color depth and operational modes.

Digital To Analog Converters Replacement Considerations

For pin-compatible replacements within the same family, consider the ADV7150 or ADV7151. Verify that the substitute supports the required 135 MHz update rate and 24-bit True Color mode. Ensure the alternative device matches the 160-lead QFP package specification.
