AD9739BBCZRL

Digital To Analog Converters Overview

The AD9739BBCZRL is a 14-bit, 2.5 GSPS high-performance RF digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It synthesizes wideband signals from DC up to 3.0 GHz using a proprietary quad-switch DAC architecture. The device features a dual-port, source synchronous LVDS interface supporting up to 1.25 GSPS data rates and includes on-chip controllers for clock domain management. It operates from 1.8 V and 3.3 V supplies, dissipates 1.16 W at maximum speed, and is housed in a 160-ball BGA package.

Digital To Analog Converters Feature Summary

• 14-bit resolution with 2.5 GSPS update rate
• Dual-port LVDS data interface with source synchronous DDR clocking
• Programmable differential output current from 8.66 mA to 31.66 mA
• On-chip synchronization controller for multichip applications

Digital To Analog Converters Applications

• Broadband communications systems
• Military jammers
• Radar and avionics
• Instrumentation and automatic test equipment

Digital To Analog Converters Procurement Notes

Verify the specific revision suffix 'BBC' against the manufacturer's official ordering guide to confirm pinout compatibility and manufacturing lot details. Ensure compliance with humidity sensitivity levels and storage conditions specified in the datasheet prior to assembly.

Digital To Analog Converters Selection Notes

Select this component for direct RF synthesis requiring bandwidths up to 1.25 GHz in baseband mode or 1.25 GHz to 3.0 GHz in mix mode. Consider the 160-ball BGA package constraints and thermal resistance of 31.2°C/W when designing the PCB layout for adequate heat dissipation.

Digital To Analog Converters Part Context

This part belongs to the AD9739 family of high-speed RF DACs. It is pin-compatible with the AD9739A variant, which lacks multichip synchronization capabilities but shares identical AC linearity and noise performance characteristics.

Digital To Analog Converters Replacement Considerations

The AD9739A is a pin-compatible alternative within the same family. Verify if multichip synchronization is required; if not, the AD9739A may be suitable.
