DNx-AI-225, DNA-AI-225, DNR-AI-225, DNF-AI-225

True 24-bit resolution makes the DNx-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). The board 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 DNx-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). 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.
