AD9760ARUZRL7

Digital To Analog Converters Overview

The AD9760ARUZRL7 is a 10-bit, 125 MSPS digital-to-analog converter 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, dissipating 175 mW at 5 V with maximum current. Key specifications include a settling time of 35 ns, integral nonlinearity (INL) of ±0.5 LSB, and differential nonlinearity (DNL) of ±0.25 LSB. It integrates edge-triggered latches and a 1.20 V bandgap reference, housed in a 28-lead TSSOP package.

Digital To Analog Converters Feature Summary

• 125 MSPS update rate with 10-bit resolution and segmented current source architecture
• Differential current outputs adjustable from 2 mA to 20 mA via external resistor
• Integrated 1.20 V temperature-compensated bandgap reference
• Single-supply operation (2.7 V to 5.5 V) with power-down mode reducing dissipation to 25 mW

Digital To Analog Converters Applications

• Communication transmit channels for basestations
• Set top boxes and digital radio links
• Direct Digital Synthesis (DDS) systems
• General instrumentation requiring low-power DACs

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix RL7 corresponds to tape-and-reel packaging when sourcing. Confirm that the AR designation indicates the industrial temperature range (-40°C to +85°C). Ensure compatibility with the 28-lead TSSOP footprint during procurement planning.

Digital To Analog Converters Selection Notes

Select this component for applications requiring high-speed conversion up to 125 MSPS with moderate 10-bit resolution. Consider the AD9760-50 variant if system requirements are limited to 50 MSPS or 60 MSPS update rates. Evaluate power consumption needs, as dissipation scales with the full-scale output current setting.

Digital To Analog Converters Part Context

This part belongs to the TxDAC product family, which includes pin-compatible 8-, 12-, and 14-bit devices. This allows for design flexibility by enabling upward or downward selection based on resolution and performance requirements without changing the PCB layout or interface logic.

Digital To Analog Converters Replacement Considerations

The AD9760-50 is a lower-performance option within the same family, guaranteed for 50 MSPS operation. Other members of the TxDAC family offer different resolutions but maintain pin compatibility.
