Digital To Analog Converters datasheet and documents for AD9767AST
Digital To Analog Converters Overview
The AD9767AST is a dual-channel, high-speed CMOS digital-to-analog converter (DAC) with 14-bit resolution. It integrates two TxDAC+ cores and a voltage reference into a 48-lead LQFP package. The device supports update rates up to 125 MSPS and operates on single supplies of 3.3 V or 5 V. Key specifications include a typical Spurious-Free Dynamic Range (SFDR) of 82 dBc at 1 MHz output, gain matching of 0.1%, and power dissipation of 380 mW at 5 V. It features differential current outputs and flexible digital interface modes.
Digital To Analog Converters Feature Summary
- 14-bit resolution with 125 MSPS maximum update rate
- Dual-port or interleaved data input modes for I/Q processing
- On-chip 1.2 V temperature-compensated bandgap voltage reference
- Nominal full-scale current of 20 mA with 0.1% channel matching
Digital To Analog Converters Applications
- Base station communications
- Digital synthesis
- Quadrature modulation
- 3D ultrasound imaging
Digital To Analog Converters Procurement Notes
Verify the specific suffix 'AST' against the manufacturer's ordering guide to confirm the exact temperature range and packaging configuration. Ensure compatibility with the required supply voltages and interface logic levels before procurement.
Digital To Analog Converters Selection Notes
Select this component when 14-bit accuracy and 125 MSPS speed are required for dual-channel applications. Consider the AD9765 or AD9763 if lower resolution is sufficient for cost reduction. Verify that the system can accommodate the 48-lead LQFP footprint and thermal requirements.
Digital To Analog Converters Part Context
The AD9767 is part of the TxDAC+ family, which includes the AD9763 (10-bit) and AD9765 (12-bit). These devices share pinouts and functionality, differing primarily in resolution. They are designed for high-performance transmit applications requiring low distortion and precise channel matching.
Digital To Analog Converters Replacement Considerations
The AD9765ASTZ and AD9763ASTZ are pin-compatible alternatives within the same series. Verify that the reduced resolution of these parts meets the system's dynamic performance requirements.
