AD9762ARU

Digital To Analog Converters Overview

The AD9762ARU is a 12-bit, 125 MSPS digital-to-analog converter (DAC) from Analog Devices' TxDAC family. It features differential current outputs with a nominal full-scale range of 2 mA to 20 mA and an output impedance exceeding 100 kΩ. The device operates on a single supply voltage between 2.7 V and 5.5 V, consuming 133 mW to 190 mW depending on configuration. Key specifications include a settling time of 35 ns, an on-chip 1.20 V reference, and edge-triggered input latches compatible with CMOS logic families.

Digital To Analog Converters Feature Summary

• 125 MSPS update rate with 12-bit resolution
• Differential current outputs adjustable from 2 mA to 20 mA
• On-chip 1.20 V temperature-compensated bandgap reference
• Single +5 V or +3 V supply operation (2.7 V to 5.5 V range)

Digital To Analog Converters Applications

• Communication transmit channels for basestations
• ADSL/HFC modems
• Direct Digital Synthesis (DDS)
• Instrumentation

Digital To Analog Converters Procurement Notes

Verify the package option RU-28 corresponds to the 28-Lead TSSOP format. Confirm the industrial temperature range (-40°C to +85°C) matches system requirements. Check datasheet Rev. B for specific electrical tolerances and thermal resistance values before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when pin compatibility with other TxDAC members (8-, 10-, 14-bit) is required for design flexibility. Choose based on the need for low power dissipation (down to 45 mW at 3 V) and high dynamic performance (SFDR up to 79 dBc). Ensure the application supports differential current output topologies or direct resistive loading within the 1.25 V compliance range.

Digital To Analog Converters Part Context

The AD9762ARU is the TSSOP package variant of the AD9762 series. It shares the same pinout and interface options as the SOIC version (AD9762AR), allowing for upward or downward selection within the TxDAC family based on resolution and cost without redesigning the PCB layout.
