1. Product profile
1.1 General description
The KMA199 is a magnetic angle sensor system. The MagnetoResistive (MR) sensor
bridges and the mixed signal Integrated Circuit (IC) are integrated into a single package.
This angular measurement system KMA199 is pre-programmed, pre-calibrated and
therefore, ready to use.
The KMA199 allows user specific adjustments of angular range, zero angle and clamping
voltages. The settings are stored permanently in an Electrically Erasable Programmable
Read-Only Memory (EEPROM).
