1. Product profile
1.1 General description
The KMA199E 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 KMA199E is pre-programmed, pre-calibrated and
therefore, ready to use.
The KMA199E 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).
