DNx-AO-333 – 32-channel, 16-bit analog output board with analog voltage readback

10yglil32-channel, 16-bit analog output board with analog voltage readback

DNx-AO-333 is a high density, high-precision, 32-channel analog voltage output board, with Guardian series diagnostics, compatible with UEI’s popular “Cube” I/O chassis. The boards offer full 16-bit resolution and guarantee monotonicity over the entire operating temperature range.



  • 32 independent 16-bit DACs
  • On-board A/D converters monitor analog output voltages
  • 10 kHz per channel max update rate
  • ±10 V output range, ±10 mA per channel
  • Per-channel offset and gain calibration
  • Simultaneous update across all channels (if desired)

The Guardian series built-in diagnostics provides on-board A/D converters allowing each analog output voltage to be monitored and confirmed. This powerful and yet simple tool sets the DNx-AO-333 apart from most D/A boards.
All 32 channels may be configured to update simultaneously, or they may be updated, one at a time, as data is written. A 1024 sample FIFO 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 DNA-AO-333 an ideal solution for generating low frequency waveforms or providing highly accurate switched stimulus.

The board also offers a digital input bit which may be used as a trigger or as a general purpose input. A digital output bit is also provided.

Software included with the DNx-AO-333 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, INtime, RT Linux, 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.
