DNx-AI-225-801 – Analog Input, Data Acquisition Board

25-channel, 24-bit, 1 kS/s per channel, simultaneous sampling analog input, data acquisition board


True 24-bit resolution makes the DNA/DNR-AI-225 an ideal data acquisition board for a wide range of precision sensors, ranging from thermocouples, to seismic detectors, strain gages, and RTDs (requires external excitation). Extremely low long-term gain and offset drifts, as well as drift vs. temperature ratio, allows the AI-225 series to be used in a wide range of applications.



  • 150 Hz low pass filter
  • 25 channels
  • 24-bit resolution
  • One channel can be used for CJC
  • 5 S/s to 1000 S/s sampling rates
  • Differential inputs of ±1.25V
  • Direct connection to thermocouples (using DNA-STP-AI-U terminal panel)
  • Ideal for seismic testing, high-precision weight and temperature measurement

The boards offer ultra-high resolution (as low as 0.5 μV at 5 Hz), true 24-bit resolution, one converter per channel with simultaneous sampling, and outstanding linearity. The DNA/DNR-AI-225 features sampling rates starting from 5Hz per channel (with 23.5 bits ENOBs) and up to 1 KHz per channel (19 bits ENOBs).
