AD9764ARZRL

Digital To Analog Converters Overview

The AD9764ARZRL is a 14-bit, 125 MSPS digital-to-analog converter (DAC) from the TxDAC family. It features differential current outputs adjustable between 2 mA and 20 mA, with power dissipation ranging from 190 mW at 5 V to 45 mW at 3 V. The device includes an on-chip 1.20 V reference and operates on a single +5 V or +3 V supply. It utilizes edge-triggered latches for data input and is housed in a 28-lead SOIC package.

Digital To Analog Converters Feature Summary

• 14-bit resolution with 125 MSPS update rate
• Differential current outputs: 2 mA to 20 mA
• On-chip 1.20 V temperature-compensated bandgap reference
• Single +5 V or +3 V supply operation

Digital To Analog Converters Applications

• Communication transmit channels
• Base stations
• ADSL/HFC modems
• Instrumentation

Digital To Analog Converters Procurement Notes

Verify that the ordering suffix ARZRL corresponds to the specific tape-and-reel packaging and RoHS compliance status defined by Analog Devices. Confirm the component matches the 28-lead SOIC physical dimensions and thermal characteristics specified in the datasheet before integration into production designs.

Digital To Analog Converters Selection Notes

Select this component when high dynamic performance, specifically SFDR and IMD, is required alongside low power consumption. The wide full-scale current adjustment allows optimization for either maximum output swing or minimum power usage. Ensure the application supports the industrial temperature range of -40°C to +85°C.

Digital To Analog Converters Part Context

The AD9764 is part of the pin-compatible TxDAC product family, which includes 8-, 10-, and 12-bit variants. This design allows for upward or downward selection based on resolution and cost requirements while maintaining identical interface options and package footprints across the series.

Digital To Analog Converters Replacement Considerations

Pin-compatible alternatives within the TxDAC family include the AD9762 (12-bit), AD9763 (10-bit), and AD9761 (8-bit). These devices share the same package and pinout but offer different resolutions and performance characteristics.
