7.1.3.3 Pseudo-Simultaneous Sampling
In absolute angle measurement, application sensor data from multiple axes are required to calculate an accurate angle. The magnetic field data collected at different times through the same signal chain introduces error in angle calculation. The TMAG5170D-Q1 offers pseudo-simultaneous sampling data collection modes to eliminate this error. Figure 7-3 shows an example where MAG_CH_EN is set at 1101b to collect XZX data. Equation 7 shows that the time stamps for the X and Z sensor data are the same.
where
- tX1, tZ, tX2 are time stamps for X, Z, X sensor data completion as defined in Figure 7-3.
Figure 7-3 XZX Magnetic Field
ConversionThe vertical X, Y sensors of the TMAG5170D-Q1 exhibit more noise than the horizontal Z sensor. The pseudo-simultaneous sampling can be used to equalize the noise floor when two set of vertical sensor data are collected against one set of horizontal sensor data, as in examples of XZX or YZY modes.
