High-Speed DAC
High-Speed DAC
Leveraging our unique low-power architecture and patents, we offer ultra-low-power CMOS Hall sensors. With high signal-to-noise ratio signal reconstruction technology, we also provide ultra-high sensitivity magnetic field sampling products.
Product Model
DAD9783
The DAD9783 features a high dynamic range, 16-bit resolution, and a dual-channel digital-to-analog converter (DAC) with a maximum sampling rate of 500 MSPS. These devices possess characteristics suitable for direct conversion transmission applications, including gain and offset compensation, and can seamlessly interface with analog quadrature modulators.
Features
- High dynamic range, dual DAC.
- Low noise and intermodulation distortion.
- Single-carrier W-CDMA ACLR = 80dBc (61.44MHz intermediate frequency ).
- The innovative switching output stage enables usable outputs exceeding the Nyquist frequency.
- LVDS inputs operate in dual-port or optional interleaved single-port mode.
- be programmed from 8.6mA to 31.7mA full scale.
- The auxiliary 10-bit current DAC has source current/sink current capability to eliminate external current. Disequilibrium Zero.
- Internally integrated 1.2V precision reference source.
- Operating power supply: 1.8V～3.3V.
- Power consumption: 320 mW.
- Small size, lead-free, 72-pin QFN package.
Applications
- Wireless infrastructure: WCDMA, CDMA2000, TD-SCDMA, WiMAX.
- Broadband communication: LMDS/MMDS, point-to-point.
- Instrumentation: Radio frequency (RF) signal generators, arbitrary waveform generators.
