DNx-AO-332-828 – 28-Channel, 16-bit Analog Output Layer

28-Channel, 16-bit Analog Output Layer

The DNx-AO-332-828 is a high density, high-precision, 28-channel analog voltage output layer available in the DNR/DNF form factors. The board offers full 16-bit resolution and guarantees monotonicity over the entire operating temperature range. Utilising an innovative per-channel digital offset and gain calibration, initial gain and offset errors are limited to ±450 μV and ±305 μV respectively.



  • 28 independent DACs
  • 16-bit resolution
  • 10 kHz per channel max update rate
  • ±10 V output range, ±10 mA per channel
  • Signal/Ground pair per channel
  • Low glitch output
  • Per-channel offset and gain calibration
  • Simultaneous update across all channels (if desired)

All 28 channels may be configured to update simultaneously, or they may be updated one at a time as data is written. A 1024 sample FIFO on each channel allows each D/A to be updated at 10 kHz without data loss. Double buffering the outputs combined with the use of low glitch D/As make the DNx-AO-332-828 an ideal solution for generating low frequency wave forms or providing highly accurate switched stimulus.
Software included with the DNx-AO-332-828 provides a comprehensive, yet easy-to-use API that supports all popular Windows programming languages as well as supporting programmers using Linux and most real-time operating systems including QNX, RTX, VXworks and more.

Finally, the UEIDAQ Framework supplies complete support for those creating applications in data acquisition software packages such as LabVIEW, MATLAB/Simulink or any application which supports ActiveX or OPC servers.
