6.3.4.2 Transient Parameters

Propagation delay (tdel_amr) is defined as the time taken for signal to propagate from magnetic input change to the sine and cosine AMR outputs. The bandwidth limitation of the internal signal conditioning amplifiers causes a phase shift on the applied magnetic field. The propagation delay increases based on the speed of the rotating field and is specified at the maximum speed of the recommended magnetic field. Figure 6-8shows an input rotating magnetic field and the response of the AMR outputs. The propagation delay in the signal path leads to a phase error.

GUID-20220701-SS0I-340K-K22Q-RHQQGJ8TNPCT-low.svg Figure 6-8 AMR Output Propagation Delay and Phase Error

The phase error (φerr) refers to the angle error between the input magnetic field and output of the sensor. This error increases with the speed of the rotating magnetic field and the propagation delay of the AMR sensor. Typically, this error can be compensated to the first order if the speed of the rotating magnetic field is known.
