ADV7127KR140

Digital To Analog Converters Overview

The ADV7127KR140 is a high-speed, monolithic CMOS digital-to-analog converter (DAC) fabricated by Analog Devices Inc. It features a 10-bit resolution and supports a maximum throughput rate of 240 MSPS. The device operates on a single 5 V or 3.3 V power 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 rate with 10-bit resolution.
• RS-343A/RS-170 compatible complementary current outputs.
• Internal voltage reference and low power standby/power-down modes.
• TTL-compatible digital inputs and single supply operation.

Digital To Analog Converters Applications

• Digital video systems (e.g., 1600 × 1200 at 100 Hz).
• High resolution color graphics displays.
• Video signal reconstruction and direct digital synthesis (DDS).

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'KR140' against the official Analog Devices ordering guide to confirm grade and packaging details. Ensure compatibility with system voltage requirements (3.3 V or 5 V) and clock frequencies up to 240 MHz. Confirm PCB layout guidelines for ground planes and decoupling are followed to maintain specified noise performance.

Digital To Analog Converters Selection Notes

Select this component for applications requiring high-speed video DAC conversion with integrated reference capabilities. Consider the 240 MHz limit for timing constraints and ensure the RSET resistor value aligns with desired full-scale output currents. Evaluate thermal dissipation within the industrial temperature range (-40°C to +85°C) during operation.
