DNx-AO-318-805 – 8-Channel isolated D/A Board optimized for best accuracy at 5V

8-Channel isolated D/A Board optimized for best accuracy at 5V


The DNx-AO-318-805 are fully isolated, high-precision, 8-channel analog voltage output board compatible with UEI’s popular “Cube”, RACKtangle and FLATRACK I/O chassis respectively. It includes the same hardware as the standard DNx-AO-318 board, but takes advantage of a special calibration routine that optimizes the boards accuracy at +5 V.



  • For use in “Cube” I/O chassis
  • 8 independent fully isolated 16-bit DACs
  • Built-in-test functionality monitors both output voltage and current
  • 10 kHz per channel max update rate
  • ±10 V output range, ±10 mA per channel
  • Optimized for maximum accuracy at 5.0V

The DNx-AO-318-805 provides extensive built-in-test diagnostics. An on-board A/D converter on each channel monitors both output voltage and current. A solid state relay on each output allows the D/A channel to be disconnected from the field I/O so that a complete board self-test can be completed without driving the circuitry connected to the outputs.
All 8 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 DNx-AO-318-805 an ideal solution for generating low frequency waveforms or providing highly accurate switched stimulus.
