ADV7120KSTZ30

Digital To Analog Converters Overview

The ADV7120KSTZ30 is a monolithic CMOS digital-to-analog video converter featuring three independent 8-bit pipeline DACs optimized for high-resolution color graphics and video systems. Operating at an 80 MHz clock rate, it converts parallel RGB pixel data into analog current outputs compatible with RS-343A and RS-170 standards without external buffering. The device integrates standard TTL input interfaces and composite sync controls (BLANK, SYNC, REF WHITE). It requires a single +5 V supply and an external 1.23 V reference voltage. Key static performance metrics include guaranteed monotonicity with ±0.5 LSB DNL and ±1 LSB INL.

Digital To Analog Converters Feature Summary

• Triple 8-bit pipeline DACs operating at 80 MHz
• TTL-compatible digital inputs and control signals
• RS-343A/RS-170 compliant analog current outputs
• Integrated composite sync, blank, and reference white controls

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific speed grade suffix against the ordering guide. The '30' suffix indicates the 30 MHz version, while the provided datasheet highlights the 80 MHz variant. Confirm package availability matches the ST-48 (TQFP) option listed for this model number.

Digital To Analog Converters Selection Notes

Select based on required clock frequency; the KSTZ30 denotes the 30 MHz speed grade. Ensure the design accommodates the 1.23 V external reference requirement and provides adequate decoupling for the +5 V analog supply. Verify that the PCB layout supports separate analog and digital ground planes to maintain specified linearity.

Digital To Analog Converters Part Context

The ADV7120 series includes variants with different speed grades (30 MHz, 50 MHz, 80 MHz) and packages (DIP, PLCC, TQFP). The KSTZ30 specifically refers to the 30 MHz version in the 48-lead Thin Quad Flatpack (TQFP) package within the industrial temperature range.
