AD9765ASTZRL

Digital To Analog Converters Overview

The AD9765ASTZRL is a dual-channel, 12-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 dynamic performance, including a typical Spurious-Free Dynamic Range (SFDR) of 81 dBc at 5 MHz output. Operating on a single 3.3 V or 5 V supply, it consumes 380 mW at full scale. Key specifications include 0.1% gain matching between channels, differential current outputs, and flexible dual-port or interleaved data input modes.

Digital To Analog Converters Feature Summary

• Dual 12-bit DACs with 125 MSPS maximum update rate
• On-chip 1.2 V temperature-compensated bandgap voltage reference
• Excellent channel matching: 0.1% gain match, <0.02% offset error
• Flexible dual-port or interleaved data interface for I/Q processing

Digital To Analog Converters Applications

• Base station communications systems
• Quadrature modulation (e.g., QAM)
• Digital synthesis
• 3D ultrasound imaging

Digital To Analog Converters Procurement Notes

Verify the 'RL' suffix indicates reel packaging when sourcing. Confirm RoHS compliance status via manufacturer documentation. Ensure availability matches project timelines as distribution status may vary by region.

Digital To Analog Converters Selection Notes

Select this component for applications requiring precise I/Q data transmission. The 12-bit resolution balances accuracy and speed. Consider the 48-lead LQFP footprint for PCB layout constraints. Verify power supply requirements align with the 3.3 V to 5 V operating range.

Digital To Analog Converters Part Context

This part belongs to the AD9763/AD9765/AD9767 family of dual TxDAC+ converters. The AD9765 specifically offers 12-bit resolution, positioned between the 10-bit AD9763 and the 14-bit AD9767. All members share pin compatibility and similar functional architectures.

Digital To Analog Converters Replacement Considerations

Pin-compatible alternatives within the same family include the AD9763 (10-bit) and AD9767 (14-bit). These parts share identical footprints and core functionality but differ in resolution and specific DC accuracy parameters.
