ADIS16480 This anomaly list describes the known bugs, anomalies, and workarounds for the ADIS16480.
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 here. FUNCTIONALITY ISSUES
Table 1. Incorrect Scale Factors for the x_DELTANG_OUT Registers and the x_DELTANG_LOW Registers [er001]
Background Issue
Workaround
Related Issues The ADIS16480 provides delta angle registers, which contain sample-to-sample angle displacement estimates for all three
axes. The x_DELTANG_OUT registers provide the upper 16 bits, and the x_DELTANG_LOW registers provide the lower 16 bits.
The x_DELTANG_OUT registers typically provide a scale factor of 720 ÷ 215 degrees per LSB, and the x_DELTANG_LOW
registers provide additional resolution (720 ÷ 231 degrees per LSB).
On units that have Firmware Revision 2.01 (or earlier), the delta angle registers do not have the same scale factors as those
listed in the ADIS16480 data sheet. For these units, the scale factors are 274 ÷ 215 degrees per LSB for x_DELTANG_OUT and
274 ÷ 231 degrees per LSB for x_DELTANG_LOW.
Use 274 ÷ 215 degrees per LSB for the x_DELTANG_OUT scale factor and 274 ÷ 231 degrees per LSB for the x_DELTANG_LOW
scale factor. Use the FIRM_REV register to determine the firmware revision of a unit. For example, FIRM_REV = 0x0201
equates to a Firmware Revision 2.01.
