ADV7127KRU140

Digital To Analog Converters Overview

The ADV7127KRU140 is a high-speed, monolithic CMOS digital-to-analog converter (DAC) fabricated by Analog Devices. It features a 10-bit resolution and a throughput rate of 240 MSPS. The device operates on a single 5 V or 3.3 V supply and includes an internal voltage reference circuit. It provides complementary analog current outputs capable of driving doubly terminated 75 Ω loads directly. The component utilizes TTL-compatible digital inputs and is housed in a 24-lead thin shrink small outline package (TSSOP).

Digital To Analog Converters Feature Summary

• 240 MSPS throughput with guaranteed monotonicity to 10 bits.
• RS-343A/RS-170 compatible complementary current outputs.
• Internal voltage reference and low power standby/power-down modes.
• TTL-compatible digital inputs for direct interface.

Digital To Analog Converters Applications

• Digital video systems (e.g., 1600 × 1200 at 100 Hz)
• High resolution color graphics
• Video signal reconstruction

Digital To Analog Converters Procurement Notes

Verify the specific grade suffix 'K' against the manufacturer's ordering guide to confirm performance specifications such as temperature range and timing limits. Ensure the TSSOP-24 footprint matches the design layout. Confirm availability status as this part number may be subject to limited supply or discontinuation notices from Analog Devices.

Digital To Analog Converters Selection Notes

Select based on required clock frequency; the K-grade variant supports up to 240 MHz. Ensure the system can accommodate the 24-lead TSSOP package dimensions. Verify that the application requires the integrated voltage reference or if an external precision reference is preferred for higher accuracy. Check power dissipation requirements against the thermal capabilities of the PCB layout.

Digital To Analog Converters Part Context

The ADV7127 series consists of high-speed video DACs designed for professional video applications. The KRU140 designation indicates a specific temperature grade and packaging configuration within the broader ADV7127 family, which also includes variants like the JRUZ240. These devices are engineered for low glitch energy and high linearity in raster scan displays.

Digital To Analog Converters Replacement Considerations

Direct replacements include other grades within the ADV7127 family, such as ADV7127JRUZ240, provided the pinout and electrical characteristics meet the design requirements. Cross-referencing the specific speed grade and package type is essential when substituting.
