ADIS16251 THEORY OF OPERATION OVERVIEW The core angular rate sensor integrated into the ADIS16251 is based on the Analog Devices iMEMS technology. This sensor operates on the principle of a resonator gyroscope. Two polysilicon sensing structures each contain a dither ...
Page 11
BASIC OPERATION The ADIS16251 is designed for simple integration into indus- trial system designs, requiring only a 5.0 V power supply and a 4-wire, industry standard serial peripheral interface (SPI). All outputs and user-programmable functions are handled by a simple ...

ADIS16251 DATA OUTPUT REGISTER ACCESS The ADIS16251 provides access to calibrated rotation measure- ments, 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. ...
Page 13
PROGRAMMING AND CONTROL CONTROL REGISTER OVERVIEW The ADIS16251 offers many programmable features controlled by writing commands to the appropriate control registers using the SPI. Table 7 provides a summary of these control registers, which controls the operation of the following ...
Page 14
ADIS16251 CALIBRATION The ADIS16251 is factory-calibrated for sensitivity and bias. It also provides several user calibration functions for simplifying field-level corrections. The calibration factors are stored in nonvolatile memory and are applied using the following linear calibration equation ...
Page 15
OPERATIONAL CONTROL Internal Sample Rate The internal sample rate defines how often data output variables are updated, independent of the rate at which they are read out on the SPI port. The SMPL_PRD register controls the ADIS16251s internal sample rate ...
