AD9762ARZRL

Digital To Analog Converters Overview

The AD9762ARZRL is a 12-bit, 125 MSPS TxDAC digital-to-analog converter manufactured by Analog Devices Inc. It features a segmented current source architecture with differential current outputs ranging from 2 mA to 20 mA. The device operates on a single supply voltage between 2.7 V and 5.5 V, consuming 175 mW at 5 V and 45 mW at 3 V. Key specifications include an INL of ±0.75 LSB and DNL of ±0.5 LSB at +25°C. It integrates a 1.20 V bandgap reference and edge-triggered latches for direct CMOS logic interfacing.

Digital To Analog Converters Procurement Notes

Verify the package option suffix in the part number against the ordering guide. The 'R' suffix indicates a 28-lead SOIC package, while 'RU' denotes a TSSOP package. Confirm that the specific reel configuration matches the required manufacturing process. Ensure the component meets RoHS3 compliance standards as specified in the datasheet.

Digital To Analog Converters Selection Notes

Select the AD9762ARZRL when a 12-bit resolution and 125 MSPS speed are required within the TxDAC family. Consider the power dissipation requirements; reducing the full-scale current lowers power consumption significantly. Verify that the load impedance and voltage compliance range align with the 1.25 V output compliance specification for optimal linearity.

Digital To Analog Converters Part Context

The AD9762 is part of the pin-compatible TxDAC product family, which includes 8-, 10-, and 14-bit variants. This design allows for upward or downward selection based on resolution and cost without changing the PCB layout. The ARZRL variant specifically utilizes the 28-lead SOIC package with lead-free termination.

Digital To Analog Converters Replacement Considerations

Pin-compatible substitutes within the TxDAC family include the AD9760 (10-bit), AD9764 (14-bit), and AD9752 (12-bit). Note that the AD9762ARURL7 is a discontinued TSSOP version of this device.
