AD9762ARUZRL7

Digital To Analog Converters Overview

The AD9762ARUZRL7 is a 12-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 bandgap reference. Key performance metrics include a settling time of 35 ns and a spurious-free dynamic range (SFDR) of up to 79 dBc at 25 MSPS. Power dissipation ranges from 45 mW at 3 V to 190 mW at 5 V, with a power-down mode reducing standby consumption to approximately 25 mW.

Digital To Analog Converters Procurement Notes

Verify the package option RU-28 (TSSOP) and industrial temperature range (-40°C to +85°C). Confirm that the RL7 suffix indicates tape and reel packaging as specified in the ordering guide. Ensure compatibility with the specific revision B datasheet requirements for external compensation capacitors when using the internal reference.

Digital To Analog Converters Selection Notes

Select this component for applications requiring pin-compatible upgrades within the TxDAC family, ranging from 8 to 14 bits. The flexible supply range supports both +3 V and +5 V systems. Consider the 20 dB adjustment span of the full-scale current for gain control or power reduction needs. Ensure output compliance limits are respected when designing load circuits.

Digital To Analog Converters Part Context

The AD9762 is part of the TxDAC product family, which includes pin-compatible 8-, 10-, 12-, and 14-bit DACs. This design allows for upward or downward selection based on resolution, performance, and cost without changing the PCB layout. The AD9762 specifically targets the 12-bit segment of this high-performance, low-power CMOS series.

Digital To Analog Converters Replacement Considerations

Pin-compatible alternatives within the same family include the AD9708 (8-bit), AD9760 (10-bit), and AD9764 (14-bit). These devices share the same interface options and package footprint, facilitating direct substitution if resolution adjustments are required.
