1. Product profile
1.1 General description
The KMA200 is an angle sensor system. The MagnetoResistive (MR) element and the
mixed signal Integrated Circuit (IC) are integrated in one package. This angle system is
already pre-programmed, offsets are compensated and therefore, ready to use.
Via the Serial Peripheral Interface (SPI) the KMA200 is user programmable. This allows
user specific adjustments of the maximum angle, zero point, clamping level and a 32-bit
identifier. The data is stored permanently in an Electrically Erasable Programmable
Read-Only Memory (EEPROM).
The device can be programmed to work either in analog or digital (SPI) output mode.
Furthermore, different analog output characteristics are possible. The resolution is better
than 0.05.
The implemented online diagnosis supervises the input and output signals as well as the
data processing. Deviations and failures of the angle value are indicated in the output
signal. Overall temperature supervision is implemented.
