AD9708ARZRL

Digital To Analog Converters Overview

The AD9708ARZRL is an 8-bit, 125 MSPS TxDAC® digital-to-analog converter manufactured by Analog Devices Inc. It features a segmented current source architecture with edge-triggered input latches and a temperature-compensated 1.2 V bandgap reference. The device supports flexible single-supply operation from +2.7 V to +5.5 V and provides differential current outputs with a nominal full-scale range of 2 mA to 20 mA. Key performance metrics include ±0.25 LSB typical DNL/INL, 35 ns settling time, and 50 dB SINAD at 5 MHz output. It is housed in a 28-lead SOIC package.

• Differential current outputs with >100 kΩ impedance

Digital To Analog Converters Applications

• Communications transmit signal paths
• Signal reconstruction systems
• Instrumentation applications

Digital To Analog Converters Procurement Notes

Verify the 'RL' suffix indicates reel packaging for surface-mount assembly. Confirm RoHS compliance status as specifications may vary by production lot. Ensure the industrial temperature range (-40°C to +85°C) meets system requirements. Check for end-of-life status or obsolescence notices from the manufacturer before finalizing procurement plans.

Digital To Analog Converters Selection Notes

Select this component when an 8-bit resolution and up to 125 MSPS update rate are required. The adjustable full-scale current allows optimization for power consumption versus dynamic performance. Ensure the design accommodates the 28-lead SOIC footprint and provides adequate thermal management given the 175 mW power dissipation at maximum settings.

Digital To Analog Converters Part Context

The AD9708 is part of the TxDAC family, which includes pin-compatible 10-, 12-, and 14-bit DACs. This family shares identical interface options and pinouts, allowing designers to scale resolution based on performance needs without changing the PCB layout. The AD9708 serves as the entry-level 8-bit option within this high-performance CMOS series.

Digital To Analog Converters Replacement Considerations

Pin-compatible alternatives within the same family include the AD9760 (10-bit), AD9777 (12-bit), and AD9779 (14-bit). These devices share the same package and interface but offer higher resolution. Verify that the increased resolution meets the specific application requirements for linearity and dynamic range.
