描述 Description

The KMA200 is an angle sensor system. The MagnetoResistive (MR) element and themixed signal Integrated Circuit (IC) are integrated with one package. This angle system isalready pre-programmed, offsets are compensated and therefore, ready to use.
Via the Serial Peripheral Interface (SPI) the KMA200 is user programmable. This allowsuser-specific adjustments of the maximum angle, zero points, clamping level and a 32-bitidentifier. The data is stored permanently in an Electrically Erasable ProgrammableRead-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 betterthan 0.05°.
The implemented online diagnosis supervises the input and output signals as well as thedata processing. Deviations and failures of the angle value are indicated in the outputsignal. Overall temperature supervision is implemented.
