Présentation

Description

The AD9744ARUZ is a 14-bit, 210 MSPS digital-to-analog converter (DAC) from Analog Devices, designed for high-speed signal generation in communications, imaging, and instrumentation.
### Key Features:
- Resolution: 14-bit
- Speed: Up to 210 MSPS
- Output: Current-sourcing (2–20 mA) with differential outputs
- Interface: Parallel CMOS/LVTTL-compatible
- Power Supply: 3.3V (digital), 1.2V/3.3V (analog)
- Package: 28-lead TSSOP
### Applications:
- Wireless basebands
- Direct digital synthesis (DDS)
- Cable modems, broadband transmitters
- Medical imaging
### Advantages:
- Low power (~185 mW at 210 MSPS)
- High dynamic performance (SFDR >80 dB at 5 MHz)
- On-chip 1.2V reference
The AD9744ARUZ is ideal for high-speed, high-resolution signal generation with efficient power consumption.
