概要

Description

The AD9764ARZ is a 14-bit, 125 MSPS digital-to-analog converter (DAC) from Analog Devices, designed for high-speed signal generation. It features excellent dynamic performance, low power consumption (~175 mW at 125 MSPS), and a dual-port interface for flexible data input.
Key specifications:
- Resolution: 14 bits
- Sampling Rate: Up to 125 MSPS
- Output: Current-sourcing (2–20 mA), requires external op-amp for voltage output.
- Interface: Parallel (8+6-bit or 14-bit), compatible with 3.3V/5V logic.
- Applications: Communications (baseband, IF), waveform synthesis, medical imaging.
The device includes an internal 1.2V reference and supports differential or single-ended operation. Its SFDR (Spurious-Free Dynamic Range) is typically 80 dBc at 1 MHz output, making it suitable for demanding RF/IF applications.
Packaged in a 28-lead SOIC, the AD9764ARZ is ideal for systems requiring high-speed, high-resolution DAC performance with low power.
For detailed usage, refer to the datasheet for timing diagrams, layout guidelines, and reference circuitry.
