Compact, Precision Ten Degrees of Freedom Inertial Sensor Silicon Anomaly ADIS16448 This anomaly list describes the known bugs, anomalies, and workarounds for the ADIS16448. Analog Devices, Inc., is committed, through future silicon revisions, to continuously improve silicon functionality. Analog Devices tries to ensure that these future silicon revisions remain compatible with your present software/systems by implementing the recommended workarounds outlined within this document. PERFORMANCE ISSUES Table 1. TEMP OUT Locks Up When Entering External Sampling Clock Mode er001 Background The ADIS16448 provides two options for driving the sampling of gyroscope, accelerometer, and temperature data: internal and external. Users can select the mode by writing either 0 (external sampling clock mode) or 1 (internal sampling clock mode) to SMPL PRD 0 . Issue When entering external sampling clock mode (writing 0x00 to SMPL PRD 7:0 ), the internal temperature measurement can lock up and fail to track changes in temperature, which in turn locks up the data in the TEMP OUT register and can cause the bias error in both gyroscopes and accelerometers to increase. Workaround If the application requires use of the external clock, read the LOT ID1 7:0 bits. If LOT ID1 7:0 0x22, this issue does not apply. If LOT ID1 7:0 < 0x22 and external clock support is a requirement, replace the unit. Related Issues None.
