AD9763ASTRL

Digital To Analog Converters Overview

The AD9763ASTRL 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 spurious-free dynamic range (SFDR) of 75 dBc at 5 MHz output. It operates on a single 3.3 V or 5 V supply, consuming 380 mW at full scale. Key features include independent or single-resistor gain control, differential current outputs, and an on-chip 1.2 V temperature-compensated bandgap reference.

Digital To Analog Converters Feature Summary

• Dual 10-bit DACs with 125 MSPS update rate
• On-chip 1.2 V temperature-compensated voltage reference
• Flexible dual-port or interleaved data input modes
• Independent or single-resistor full-scale current setting

Digital To Analog Converters Applications

• Base station communications
• Digital synthesis
• Quadrature modulation
• 3D ultrasound imaging

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'ASTZRL' against the manufacturer's official documentation to confirm tape-and-reel packaging and lead-free status. Ensure compatibility with the required operating temperature range of -40°C to +85°C. Cross-reference the part number with the latest datasheet revision G to confirm pinout and electrical specifications match design requirements.

Digital To Analog Converters Selection Notes

Select the AD9763 for applications requiring 10-bit resolution at high speeds. Consider the AD9765 or AD9767 if higher resolution (12-bit or 14-bit) is needed, as they share the same pinout and form factor. Evaluate power consumption needs; the device consumes 380 mW at 5 V but can enter a low-power sleep mode. Ensure the system supports the parallel digital interface and differential current output configuration.

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 designed for transmit applications in communication systems. They offer pin-compatible upgrades within the family, allowing designers to scale resolution without changing the PCB layout. The AD9763 specifically targets cost-sensitive applications requiring 10-bit performance.

Digital To Analog Converters Replacement Considerations

The AD9765 and AD9767 are pin-compatible replacements offering higher resolutions (12-bit and 14-bit respectively). Verify that the increased resolution meets system requirements and that the power budget accommodates any differences in consumption. No other direct substitutes are documented in the provided source material.
