AD9764ARUZRL7

Digital To Analog Converters Overview

The AD9764ARUZRL7 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 edge-triggered input latches and an internal 1.20 V temperature-compensated bandgap reference. Key electrical specifications include a settling time of 35 ns (to 0.1%), INL of ±2.5 LSB at +25°C, and DNL of ±1.5 LSB at +25°C. Power dissipation ranges from 45 mW at 3 V to 190 mW at 5 V.

Digital To Analog Converters Feature Summary

• Differential current outputs adjustable from 2 mA to 20 mA
• Integrated 1.20 V bandgap reference and edge-triggered latches
• Single-supply operation (2.7 V to 5.5 V) with power-down mode

Digital To Analog Converters Applications

• Communication transmit channels for basestations
• ADSL/HFC modems
• Instrumentation systems

Digital To Analog Converters Procurement Notes

Verify the package type matches the RU suffix (TSSOP-28). Confirm RoHS compliance status via the Z suffix if required. Check the specific revision level against the latest datasheet to ensure parameter consistency. Validate that the ordering code corresponds to the reel packaging format.

Digital To Analog Converters Selection Notes

Select based on required resolution and update speed within the TxDAC family. Ensure the output current setting aligns with power dissipation limits. Verify logic voltage compatibility (+3 V or +5 V CMOS) for digital inputs. Consider thermal resistance characteristics for the TSSOP package in high-density designs.

Digital To Analog Converters Part Context

This component belongs to the TxDAC product family, which includes pin-compatible 8-, 10-, and 12-bit variants. The AD9764 serves as the 14-bit member, offering higher resolution while maintaining the same interface options and package footprint. This allows for flexible component selection based on performance and cost requirements without redesigning the PCB layout.

Digital To Analog Converters Replacement Considerations

Pin-compatible alternatives within the TxDAC family include the AD9708 (8-bit), AD9760 (10-bit), and AD9762 (12-bit). These devices share the same 28-lead SOIC/TSSOP packages and interface but offer different resolutions and performance profiles.
