11.2.5 Sensitivity polarity (PLATEPOL)

The polarity of the sensitivity can be programmed by changing the value of the PLATEPOL bit

PLATEPOL

Polarity

0

Positive

1

Negative

Please note that the factory calibration is done with PLATEPOL=0 . Melexis cannot guarantee the magnetic

specification if this parameter is changed during customer calibration.

11.2.6 Clamping Level Programming (CLAMPLOW, CLAMPHIGH)

The clamping levels limit the maximum and minimum output levels. The clamping levels are ratiometric (if

RATIODIS = 0). The CLAMPLOW parameter adjusts the minimum output voltage level from 5%...10%Vdd.

The CLAMPHIGH parameter sets the maximum output voltage level from 90...95%Vdd.
