AD9767ASTRL

Digital To Analog Converters Overview

The AD9767ASTRL is a dual-channel, 14-bit CMOS digital-to-analog converter (DAC) from Analog Devices. It integrates two high-performance TxDAC+ cores, an on-chip 1.2 V voltage reference, and digital interface circuitry within a 48-lead LQFP package. The device supports update rates up to 125 MSPS with excellent linearity, featuring differential current outputs. It operates on a single 3.3 V or 5 V supply, consuming 380 mW at full scale. Key specifications include a typical SFDR of 75 dBc at 5 MHz output and gain matching of 0.1%. The part is designed for applications requiring precise I/Q data processing.

Digital To Analog Converters Feature Summary

• 14-bit resolution with 125 MSPS maximum update rate
• Dual-port or interleaved digital interface modes
• On-chip 1.2 V temperature-compensated bandgap reference
• Differential current outputs with 20 mA nominal full-scale current

Digital To Analog Converters Applications

• Communications base stations
• Digital synthesis systems
• Quadrature modulation circuits
• 3D ultrasound imaging equipment

Digital To Analog Converters Procurement Notes

Verify the ordering suffix 'RL' indicates reel packaging when sourcing components. Confirm that the specific revision matches the required date code for gain control mode configurations. Ensure compatibility with the 48-lead LQFP footprint during PCB layout planning.

Digital To Analog Converters Selection Notes

Select this model for applications requiring 14-bit precision at high speeds. Compare against AD9765 (12-bit) or AD9763 (10-bit) if lower resolution suffices for cost reduction. Verify power supply requirements align with the 3.3 V to 5 V operating range and check thermal dissipation needs for the LQFP package.

Digital To Analog Converters Part Context

This component belongs to the AD9763/AD9765/AD9767 family of dual transmit DACs. All members share pin compatibility and core architecture, differing primarily in resolution. The AD9767 represents the highest resolution variant in this series, offering 14-bit accuracy while maintaining the same 125 MSPS performance envelope.

Digital To Analog Converters Replacement Considerations

Pin-compatible alternatives within the same family include the AD9765 (12-bit) and AD9763 (10-bit). These parts share identical footprints and functionality but offer reduced resolution. No other cross-family replacements are confirmed.
