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.
