D.Module2.ADDA8M12

The D.Module2.ADDA8M12 is based on the Texas Instruments data converters THS12082 and DAC7821. The analog front end simultaneously digitizes two single-ended voltage inputs with 12-bit resolution and sampling rates up to 8Msps. The two DAC outputs also deliver 12-bit resolution. Fifo-buffering simplifies the DSP interface. In the D.Module2 family it can be used with a vertically stacking DSP module, or with vertically stacked DSP and FPGA modules.

Key Features

  • simultaneous sampling up to 8MS/s
  • 2 inputs, 2 outputs
  • 12-bit resolution
  • 32-bit parallel DSP interface with fifo
  • low latency
  • input range 1V

Applications

The D.Module2.ADDA8M12 is suited for data acquisition in non-destructive material inspection systems (based on ultrasonics or eddy-current), as well as IF (intermediate frequency) subsampling in radio and radar equippment. The short acquisition time also makes the ADDA8M12 a good choice for fast control loops and servo-positioning systems requiring minimum latency.
