¹α_UNCORRis 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.

²α_CALis 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 T_A= 25°C. Error components such as amplitude synchronism drift, amplifier gain matching, thermal offset drift, phase error, hysteresis, orthogonality error, and

noise are included.

³Guaranteed through characterization.

⁴α_DYNAMICis 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.

⁵Angular speed <300 rpm. Limited to 180° rotation. The value is calculated only with the third and fifth harmonics of the spectrum of output signal amplitude by the

ideal homogeneous field.

⁶Peak-to-peak amplitude mismatch. k = 100 × VSIN/VCOS.

⁷Rotation frequency dependent phase error, after offset correction, amplitude calibration, and arctan calculation.
