Product data sheet
Since the Anisotropic MR (AMR) effect is periodic over 180°, the sensor output is also
180°-periodic, where the angle is calculated relative to a freely programmable zero angle.
The dashed line indicates the mechanical zero degree position.
The KMA199 provides one analog output signal on pin OUT/DATA. The measured angle
α is converted linearly into a value, which is ratiometric to the supply voltage V
positive or a negative slope is provided for this purpose.
The following table describes the analog output behavior for a positive slope. If for
example, a magnetic field angle, above the programmed maximum angle α
the clamp switch angle α
upper clamping voltage. If the magnetic field angle is larger than the clamp switch angle,
the analog output switches from upper to lower clamping voltage. In the case of a
negative slope, the clamping voltages are changed.
Table 3.
The analog output voltage range codes both angular and diagnostic information. A valid
angle value is between the upper and lower clamping voltage. If the analog output is in the
diagnostic range, that is below 4 %V
detected. The analog output repeats every 180°.
