The ADAC250 FMC is designed around the high-performance A/D and D/A conversion technology from Texas Instruments — it integrates one dual, 14-bit, 250 MSPS analog-to-digital converter (ADS62P49) and a dual, 16-bit, 1 GSPS digital-to-analog converter (DAC5682Z - also capable of a 2–4× interpolation mode). Combined with multiple clocks and synchronization modes, the ADAC250 is at its best in DSP applications such as software-defined radio (SDR), advanced telecommunications (MIMO systems, cognitive radios, beamformers, LTE, WiMAX), signal intelligence (SIGINT), radar, sonar, and medical imaging applications.
