AD9763ASTZRL

Digital To Analog Converters Overview

The AD9763ASTZRL is a dual-channel, 10-bit digital-to-analog converter (DAC) from Analog Devices. It features a maximum update rate of 125 MSPS and operates on a single 3 V to 5.5 V supply. The device integrates two TxDAC+ cores, an internal 1.2 V reference, and digital interface logic within a 48-lead LQFP package. Key electrical parameters include a settling time of 35 ns, a nominal full-scale output current of 20 mA, and power dissipation of 380 mW at 5 V. It supports parallel data interfaces with independent or interleaved input modes.

Digital To Analog Converters Feature Summary

• Dual 10-bit DACs with 125 MSPS update rate
• Integrated 1.2 V temperature-compensated bandgap reference
• Flexible dual-port or interleaved data interface
• Independent or single-resistor gain control for full-scale current

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 'TZRL' against the manufacturer's ordering guide to confirm reel packaging and RoHS compliance status. Ensure the source document explicitly lists this part number variant as available. Cross-reference the date code requirements if independent gain control via external resistors is required, as feature availability may depend on manufacturing date codes.

Digital To Analog Converters Selection Notes

Select the AD9763ASTZRL when a 10-bit resolution is sufficient for I/Q data processing in high-speed applications. Compare against the AD9765 (12-bit) and AD9767 (14-bit) if higher dynamic range is needed, noting they share pinouts. Verify that the 125 MSPS clock speed meets the system bandwidth requirements and that the 380 mW power dissipation fits the thermal design constraints.

Digital To Analog Converters Part Context

This component belongs to the AD9763/AD9765/AD9767 family of dual transmit DACs. These devices are designed for communications applications requiring optimized I and Q data handling. They utilize a segmented current source architecture with proprietary switching to minimize glitch energy. The family offers pin compatibility across different resolutions while maintaining identical package dimensions and interface logic.

Digital To Analog Converters Replacement Considerations

The AD9765ASTZRL and AD9767ASTZRL are pin-compatible alternatives offering 12-bit and 14-bit resolutions respectively. Substitution requires verification that the increased bit depth does not exceed the system's digital interface capabilities or power budget.
