ADV7120KST30-REEL

Digital To Analog Converters Overview

The ADV7120KST30-REEL is a CMOS triple 8-bit video digital-to-analog converter (DAC) designed for high-resolution color graphics and video systems. It features three independent 8-bit DACs for Red, Green, and Blue channels with an 80 MHz pipelined operation speed. The device accepts standard TTL-compatible digital inputs and provides high-impedance analog current outputs compatible with RS-343A and RS-170 standards. It operates on a single +5 V supply and requires an external 1.23 V reference voltage. The component is housed in a 48-lead Thin Quad Flatpack (TQFP) package.

Digital To Analog Converters Feature Summary

• Triple 8-bit D/A converters with 80 MHz pipelined operation

• Standard TTL compatible digital input interface
• Monolithic +5 V CMOS construction

Digital To Analog Converters Applications

• High resolution color graphics systems
• CAE/CAD/CAM applications
• Image processing instrumentation
• Video signal reconstruction
• Direct Digital Synthesis (DDS) and I/Q modulation

Digital To Analog Converters Procurement Notes

Verify the specific speed grade associated with the KST30 suffix against the manufacturer's ordering guide to confirm the 30 MHz clock rate specification. Ensure the reel packaging matches the required manufacturing line configuration. Confirm that the industrial temperature range of 0°C to +70°C aligns with the target system environment requirements.

Digital To Analog Converters Selection Notes

Select this component when a low-cost, high-speed triple DAC is required for RGB video generation. The device supports direct driving of doubly terminated 75 Ω coaxial cables without external buffering. Designers must provide an external 1.23 V reference and connect a compensation capacitor between the COMP and VAA pins. Unused channels should be terminated with appropriate loads to maintain performance.

Digital To Analog Converters Part Context

The ADV7120 series includes variants with different speed grades, including 30 MHz, 50 MHz, and 80 MHz versions. The KST30 designation specifically indicates the 30 MHz speed grade within the TQFP package family. Other package options include 40-pin DIP and 44-pin PLCC configurations for different board space constraints.

Digital To Analog Converters Replacement Considerations

The ADV7120KP30 and ADV7120KN30 are alternative package versions of the same 30 MHz functional device. No direct pin-compatible replacements from other manufacturers are documented in the provided source material.
