signal. After that consecutive output edges should have a nominal delay of about 180°.
In rare cases one further switching of PGA can occur (see Appendix B).
During the uncalibrated mode the offset value is calculated by the peak detection
algorithm as described in the TLE4941 Data Sheet.
Transition to Calibrated Mode
In the calibrated mode the output will switch at zero-crossing of the input signal. The
phase shift between input and output signal is no longer determined by the ratio between
digital noise constant and signal amplitude. Therefore a sudden change in the phase
shift may occur during the transition from uncalibrated to calibrated mode.
Calibrated Mode
See TLE4941 Data Sheet.
Additional Notes
Unlike the TLE4941 the first output edge might occur before the first zero-crossing of the
magnetic input signal. However, referring to the input signal the delay between start-up
of the signal and first calibrated output signal is identical with TLE4941.
Typically the phase error due to PGA-transition reduces the error caused by switching
the mode from uncalibrated to calibrated. PGA-transition usually takes place on the first
full magnetic edge.
The summed up change in phase error from the first output edge issued to the output
edges in calibrated mode will not exceed ± 90°.
