Dual 12-Bit 250 MSPS Digital-to-Analog Converters

Product Details

The AD9743/AD9745/AD976/AD9747 are pin-compatible, high dynamic range, dual digital-to-analog converters (DACs) with 10-/12-/14-/16-bit resolutions and sample rates of up to 250 MSPS. The devices include specific features for direct conversion transmit applications, including gain and offset compensation, and they interface seamlessly with analog quadrature modulators, such as the ADL5370.

A proprietary, dynamic output architecture permits synthesis of analog outputs even above Nyquist by shifting energy away from the fundamental and into the image frequency.

A serial peripheral interface (SPI) port provides full programmability. In addition, some pin-programmable features are offered for those applications without a controller.

Product Highlights

  1. Low noise and intermodulation distortion (IMD) enables high quality synthesis of wideband signals.
  2. Proprietary switching output for enhanced dynamic performance.
  3. Programmable current outputs and dual auxiliary DACs provide flexibility and system enhancements.


  • Wireless infrastructure:
  • Wideband communications:
