1 αUNCORR is the total mechanical angular error after arctan computation. This parameter is 100% production tested at 25°C and 150°C. This error includes all sources of  
error over temperature before calibration. Error components such as offset, amplitude synchronism, amplitude synchronism drift, thermal offset drift, phase error,  
hysteresis, orthogonality error, and noise are included.  
2 αCAL is the total mechanical angular error after arctan computation. This error includes all sources of error over temperature after an initial offset (nulling) is performed  
at TA = 25°C. Error components such as amplitude synchronism drift, amplifier gain matching, thermal offset drift, phase error, hysteresis, orthogonality error, and  
noise are included.  
3 Guaranteed through characterization.  
4 αDYNAMIC is the total mechanical angular error after arctan computation. This parameter is 100% production tested. This error includes all sources of error over  
temperature after a continuous background calibration is performed to correct offset and amplitude synchronism errors. Error components such as phase error,  
hysteresis, orthogonality error, noise, and lifetime drift are included.  
5 Peak-to-peak amplitude mismatch. k = 100 × VSIN/VCOS.  
6 Rotation frequency dependent phase error, after offset correction, amplitude calibration, and arctan calculation.
