1. Product profile
1.1 General description
The KMA221 is a magnetic angle sensor module. The MagnetoResistive (MR) sensor
bridges, the mixed signal Integrated Circuit (IC) and the required capacitors are integrated
into a single package.
This angular measurement module KMA221 is pre-programmed, pre-calibrated and
therefore, ready to use.
The KMA221 allows user-specific adjustments of angular range, zero angle and clamping
voltages. The settings are stored permanently in a non-volatile memory.
