AD9786:  16-Bit, 500 MSPS TxDAC+® D/A Converter

Product Details

Newer Alternatives:
  • AD9125: Dual, 16-Bit, 1000 MSPS, TxDAC+® Digital-to-Analog Converter
  • AD9779A: Dual 16-Bit, 1 GSPS, Digital-to-Analog Converter

The AD9786 is the 16-bit member of the latest high-performance TxDAC+® product family. Designed specifically to address multicarrier communications architectures, it achieves true 16-bit linearity and breakthrough noise and intermodulation distortion performance. This record-breaking performance allows synthesis of multicarrier transmit signals at intermediate frequencies (IFs) of 100 to 300 MHz and beyond. As a result, system designers can eliminate an up-conversion stage and reduce overall parts count, ultimately lowering total system cost. Its 2x/4x/8x selectable interpolation filters ease data rate and output signal reconstruction filter requirements.
