ADV7127KRUZ50-REEL

Digital To Analog Converters Overview

The ADV7127KRUZ50-REEL is a high-speed, single-channel 10-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It operates with a throughput rate of up to 240 MSPS and supports both 3.3 V and 5 V single-supply configurations. The device features TTL-compatible digital inputs, an internal voltage reference circuit, and complementary current outputs capable of driving doubly terminated 75 Ω loads directly. Packaged in a 24-lead thin shrink small outline package (TSSOP), it includes power-down and standby modes for low-power operation within the industrial temperature range of −40°C to +85°C.

Digital To Analog Converters Feature Summary

• 240 MSPS maximum throughput rate with guaranteed monotonicity to 10 bits
• RS-343A/RS-170 compatible analog output with integrated voltage reference
• TTL-compatible data and clock inputs for direct interface with logic systems
• Low power consumption with dedicated PSAVE and PDOWN control pins

Digital To Analog Converters Applications

• Digital video systems supporting resolutions up to 1600 × 1200 at 100 Hz
• High resolution color graphics displays
• Video signal reconstruction and direct digital synthesis (DDS)
• Wireless local area networks (LANs) and digital radio modulation

Digital To Analog Converters Procurement Notes

Verify that the REEL suffix indicates tape-and-reel packaging rather than tube packaging when sourcing components. Confirm the specific speed grade matches system requirements, as timing specifications vary between 50 MHz, 140 MHz, and 240 MHz grades. Ensure the ordering code corresponds to the correct voltage supply configuration intended for the design.

Digital To Analog Converters Selection Notes

Select this component for applications requiring high-speed conversion with minimal external reference circuitry due to the on-board voltage reference. Consider the 24-lead TSSOP package constraints for PCB layout, particularly regarding ground plane separation and decoupling capacitor placement near VAA and GND pins. Verify that the TTL input levels align with the host processor's logic family to ensure reliable data latching on the rising clock edge.

Digital To Analog Converters Part Context

This part belongs to the ADV7127 series of CMOS high-speed video DACs. The KRUZ50 designation typically denotes a specific speed bin and packaging variant within the broader product line. The device shares architectural similarities with other members like the ADV7127JR240 but differs in manufacturing lot or performance grading parameters defined by the manufacturer.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible substitutes include the ADV7127JR240 and ADV7127KR50. When replacing, verify that the new part meets the required clock frequency specifications and that the RSET resistor value maintains the desired full-scale output current according to the datasheet equation.
