AD9763ASTZ

Digital To Analog Converters Overview

The AD9763ASTZ is a dual-port, high-speed, 2-channel, 10-bit CMOS digital-to-analog converter (DAC) from Analog Devices. It integrates two TxDAC+ cores, a voltage reference, and digital interface circuitry into a 48-lead LQFP package. The device supports an update rate of up to 125 MSPS with excellent SFDR performance of 75 dBc at 5 MHz output. It operates on a single supply of 3.3 V or 5 V, consuming 380 mW at full scale. Key features include differential current outputs, on-chip 1.2 V reference, and flexible dual-port or interleaved data input modes.

Digital To Analog Converters Feature Summary

• Dual 10-bit DACs with 125 MSPS maximum update rate
• Excellent gain and offset matching: 0.1% typical
• On-chip 1.2 V temperature-compensated band gap reference
• Flexible dual-port or interleaved data interface

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'ASTZ' against the manufacturer's ordering guide to confirm the exact temperature range and packaging details. Ensure compatibility with the required 48-lead LQFP footprint and check for any recent revision history updates that may affect pin functions or electrical specifications.

Digital To Analog Converters Selection Notes

Select the AD9763ASTZ when 10-bit resolution is sufficient for the application, as opposed to the 12-bit AD9765 or 14-bit AD9767 variants which share the same pinout. Consider the 380 mW power dissipation at 5 V operation and ensure adequate thermal management for the LQFP package in the final design.

Digital To Analog Converters Part Context

The AD9763 is part of the TxDAC+ family, which includes the AD9765 (12-bit) and AD9767 (14-bit). These devices are pin-compatible and designed for high-performance transmit applications. They utilize a segmented current source architecture to minimize glitch energy and maximize dynamic accuracy.

Digital To Analog Converters Replacement Considerations

Pin-compatible alternatives within the same family include the AD9765ASTZ and AD9767ASTZ, offering higher resolution but identical physical interfaces. Verify if the increased resolution is necessary for the specific signal processing requirements.
