ADIS16250/ADIS16255 DATA OUTPUT REGISTER ACCESS The ADIS16250/ADIS16255 provide access to calibrated rotation measurements, relative angle estimates, power supply measurements, temperature measurements, and an auxiliary 12-bit ADC channel. This output data is continuously updating internally, regardless of user read rates. The ...

ADIS16250/ADIS16255 CALIBRATION The ADIS16250/ADIS16255 are factory-calibrated for sensitivity and bias. It also provides several user calibration functions for simplifying field-level corrections. The calibra- tion factors are stored in nonvolatile memory and are applied using the following linear calibration equation: y ...
