AD9764ARURL

Digital To Analog Converters Overview

The AD9764ARURL is a 14-bit, 125 MSPS TxDAC® digital-to-analog converter manufactured by Analog Devices Inc. It features differential current outputs with a nominal full-scale range of 2 mA to 20 mA and operates on a single supply voltage between 2.7 V and 5.5 V. The device integrates a 1.20 V temperature-compensated bandgap reference and edge-triggered input latches. Key performance metrics include an INL of ±2.5 LSB and DNL of ±1.5 LSB at +25°C. Power dissipation is 190 mW at 5 V with 20 mA output, reducible to 45 mW at 3 V or 25 mW in power-down mode.

Digital To Analog Converters Procurement Notes

Verify the specific package type associated with the URL suffix against the manufacturer's ordering guide. Confirm RoHS compliance status and lead times directly with authorized distributors or Analog Devices, as availability varies by region and production cycle.

Digital To Analog Converters Selection Notes

Select this component for applications requiring high dynamic performance in a low-power CMOS DAC. The wide full-scale current adjustment allows optimization for power consumption versus signal swing. Ensure the load impedance matches the output compliance range of 1.25 V to maintain specified linearity.

Digital To Analog Converters Part Context

The AD9764 is part of the TxDAC® family, which includes pin-compatible 8-, 10-, and 12-bit variants. This family is optimized for communication transmit paths, sharing identical interface options and package footprints to facilitate design upgrades or cost reductions based on resolution requirements.

Digital To Analog Converters Replacement Considerations

Pin-compatible alternatives within the TxDAC family include the AD9742 (12-bit), AD9744 (10-bit), and AD9746 (8-bit). Cross-vendor substitutes require verification of interface compatibility, update rates, and output current specifications.
