ADV7123KSTZ140-RL

Digital To Analog Converters Overview

The ADV7123KSTZ140-RL is a triple high-speed video digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It integrates three independent 10-bit DACs on a single monolithic CMOS chip, supporting a maximum throughput rate of 140 MSPS. The device features TTL-compatible inputs, complementary analog outputs, and an internal 1.235 V voltage reference. It operates on a single 5 V or 3.3 V supply and includes low-power standby modes. Designed for industrial applications, it functions within a temperature range of −40°C to +85°C and is housed in a 48-lead LQFP package.

Digital To Analog Converters Feature Summary

• Triple 10-bit DAC architecture with 140 MSPS throughput
• RS-343A/RS-170 compatible differential and single-ended outputs
• Internal 1.235 V reference and TTL-compatible digital interface
• Low power dissipation: 30 mW minimum at 3 V operation

Digital To Analog Converters Applications

• Digital video systems
• High resolution color graphics
• Video signal reconstruction

Digital To Analog Converters Procurement Notes

Verify the specific speed grade suffix '140' against the manufacturer's current ordering guide to confirm the 140 MHz performance specification. Ensure the lead-free (Pb-free) packaging matches project requirements. Confirm availability status directly with authorized distributors as supply levels may vary.

Digital To Analog Converters Selection Notes

Select this component when a 140 MHz sampling rate is sufficient for the target video application. Compare against the standard ADV7123 (330 MHz) if higher bandwidth is required, or lower-grade variants if cost reduction is prioritized over speed. Verify that the 10-bit resolution meets the system's dynamic range needs.

Digital To Analog Converters Part Context

This part belongs to the ADV7123 family of high-speed video DACs from Analog Devices. The 'KSTZ' designation indicates the 48-lead LQFP package and lead-free construction. The '140' suffix specifies the operational frequency grade, distinguishing it from the 50 MHz, 240 MHz, and 330 MHz versions available in the same product line.

Digital To Analog Converters Replacement Considerations

Direct replacements include other speed grades of the ADV7123 series (e.g., ADV7123JSTZ for 50 MHz, ADV7123BSTZ for 240 MHz, ADV7123CSTZ for 330 MHz) provided the pinout and electrical characteristics are compatible with the existing design.
