    ADIS16448 Silicon Anomaly
    Docket ↓
    Silicon Anomaly Compact, Precision
    Ten Degrees of Freedom Inertial Sensor
    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]
    Related Issues 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].
    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.
    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.
