AD9762ARUZ

Digital To Analog Converters Overview

The AD9762ARUZ is a 12-bit, 125 MSPS TxDAC digital-to-analog converter in a 28-lead TSSOP package. It features a segmented current source architecture with differential current outputs (IOUTA/IOUTB) ranging from 2 mA to 20 mA. The device operates on a single supply of 2.7 V to 5.5 V and includes an on-chip 1.20 V bandgap reference. Key specifications include ±2.5 LSB INL and ±1.5 LSB DNL at +25°C, with power dissipation of 175 mW at 5 V. It supports edge-triggered latching for direct CMOS interfacing.

Digital To Analog Converters Feature Summary

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

Digital To Analog Converters Applications

• Communication transmit channels
• Base station multichannel applications
• ADSL/HFC modems
• Direct Digital Synthesis (DDS)
• Instrumentation

Digital To Analog Converters Procurement Notes

Verify the suffix 'RUZ' corresponds to the 28-lead TSSOP package and industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the ordering part number matches the specific revision required for the design.

Digital To Analog Converters Selection Notes

Select based on required resolution and speed; this model offers 12 bits at 125 MSPS. Consider the adjustable full-scale current (2–20 mA) for power optimization or gain control needs. Verify interface compatibility with edge-triggered latches for +3 V or +5 V CMOS logic families.

Digital To Analog Converters Part Context

The AD9762 is part of Analog Devices' TxDAC family, which includes pin-compatible 8-, 10-, 12-, and 14-bit DACs. This allows for upward or downward component selection within the same package footprint based on performance and cost requirements without redesigning the PCB layout.

Digital To Analog Converters Replacement Considerations

Publicly confirmed substitutes are not available in the provided datasheet. The AD9762 is pin-compatible with other members of the TxDAC family (e.g., AD9750, AD9764) for resolution adjustments.
