ADV7120KST50

Digital To Analog Converters Overview

The ADV7120KST50 is a CMOS, triple 8-bit video digital-to-analog converter (DAC) operating at a maximum clock rate of 50 MHz. It integrates three independent high-speed D/A converters for Red, Green, and Blue channels, alongside standard TTL-compatible input interfaces and high-impedance analog output current sources. The device requires a single +5 V supply and an external 1.23 V reference voltage. Designed for high-resolution color graphics and video systems, it generates RGB signals compatible with RS-343A and RS-170 standards without external buffering. 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 50 MHz pipelined operation
RS-343A/RS-170 compatible outputs requiring no external buffering
Standard TTL compatible inputs for data and control signals
+5 V CMOS monolithic construction ensuring low power dissipation

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 suffix '50' to confirm the 50 MHz operational limit, as other variants like '80' or '30' exist within the same family. Ensure the TQFP package option matches the design footprint requirements. Confirm that the industrial temperature range version is not required, as the standard part operates from 0°C to +70°C.

Digital To Analog Converters Selection Notes

Select this model when a 50 MHz update rate is sufficient for the target display resolution. An external 1.23 V voltage reference, such as the AD589, is mandatory for proper operation. Designers must account for the internal reference amplifier compensation by connecting a 0.1 μF capacitor between the COMP and VAA pins. Ensure the PCB layout separates analog and digital ground planes to maintain signal integrity.

Digital To Analog Converters Part Context

The ADV7120 series includes multiple speed grades: ADV7120KN80/KP80 (80 MHz), ADV7120KN50/KP50 (50 MHz), and ADV7120KN30/KP30 (30 MHz). The KST50 variant specifically denotes the 50 MHz speed grade packaged in a 48-lead TQFP. Other packages include 40-pin DIP and 44-pin PLCC options for different board space constraints.
