AD9764ARURL7

Digital To Analog Converters Overview

The AD9764ARURL7 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. Packaged in a 28-lead TSSOP, it utilizes a segmented current source architecture for enhanced dynamic performance.

Digital To Analog Converters Procurement Notes

Verify the specific package type against project requirements, as the AD9764 family includes both SOIC and TSSOP variants. Confirm RoHS compliance status for the specific revision ordered. Ensure that the ordering suffix matches the required packaging format, such as tape and reel quantities if applicable for automated assembly processes.

Digital To Analog Converters Selection Notes

Select this component when high-resolution DAC performance is required for communication signal paths. The wide full-scale current adjustment allows optimization for power consumption versus output swing. Verify that the system logic levels are compatible with the integrated edge-triggered latches for direct interfacing with +3 V or +5 V CMOS families.

Digital To Analog Converters Part Context

The AD9764 is the 14-bit member of the pin-compatible TxDAC product family, which also includes 8-, 10-, and 12-bit devices. This compatibility allows designers to scale resolution based on performance and cost requirements without changing the interface options or physical footprint. The series is optimized for transmit signal paths in communication systems.

Digital To Analog Converters Replacement Considerations

Pin-compatible alternatives within the TxDAC family include the AD9752 (12-bit), AD9754 (10-bit), and AD9708 (8-bit). These devices share the same interface and package but offer different resolutions. Verify that the lower resolution meets the system's dynamic performance specifications before substitution.
