The AD9780/AD9781/AD9783 are pin compatible, high dynamic range, 12/14/16 bit resolution, and dual channels, respectively
Digital-to-analog converters(DAC) with sampling rates up to 500 MSPS. These devices have features suitable for direct conversion transmission applications, including gain and offset compensation, and can be combined with
ADL5370and other analog quadrature modulators seamless interface.
The proprietary dynamic output architecture moves energy from the fundamental frequency to the image frequency, allowing the analog output to be synthesized even above the Nyquist frequency.
Full programming is provided through a serial peripheral interface (SPI) port, and pin-programmable features are also available for controllerless applications.
Product features
- With low noise and intermodulation distortion (IMD), wideband signals can be synthesized with high quality.
- Proprietary switching outputs enhance dynamic performance.
- Programmable current outputs and dual auxiliary DACs provide flexibility while enhancing system functionality.
