Description

The AD9751AST is a 10-bit, 125 MSPS digital-to-analog converter (DAC) from Analog Devices, designed for high-speed signal generation. It features a current-output architecture with a 2x interpolation filter, reducing input data rate requirements.
Key specifications:
- Resolution: 10 bits
- Sampling Rate: Up to 125 MSPS
- Output: Differential current (2–20 mA)
- Power Supply: +5V or +3.3V operation
- Package: 28-lead SOIC (AST suffix)
Applications include communications, video, and waveform synthesis. The on-chip PLL simplifies clocking, while a sleep mode reduces power consumption when idle.
For detailed performance metrics, refer to the datasheet.
