Table 1. Alarm Variation with Temperature [er001]
Background
Issue
Workaround
Related Issues The ADIS16136 provides user-programmable alarms for monitoring.
On units that have earlier date codes than 1146, the alarm trip points vary with temperature when using the unfiltered data
option (ALM_CTRL[3] = 0).
On units that have earlier date codes than 1146, use the filtered data option (set ALM_CTRL[3] = 1) to achieve best stability in the
alarm trip points. On units that have date codes of 1146 or later, this issue has been fixed
None. Table 2. GYRO_OUT Oscillation [er002]
Background Issue
Workaround
Related Issues The ADIS16136 provides angular rate output data through two registers: GYRO_OUT and GYRO_OUT2. GYRO_OUT
represents the upper 16-bits of the angular rate data, while GYRO_OUT2 represents up the lower bits. The bits in
GYRO_OUT2 capture the bit growth associated with the averaging/decimation filter stage. When the decimation rate is
equal to zero, the bits in GYRO_OUT2 will not represent angular rate information. In general, this register configuration
preserves a normal distribution for the noise that has an even distribution on each side of the gyroscope’s bias. …
