General description
The KMA320/A is a dual channel magnetic angle sensor. Magnetoresistive (MR) sensor
bridges and mixed signal ICs are integrated into a single package. The module has
integrated filters and is optimized for PCB-less designs. The KMA320/A dual channel
sensor module has common power supply terminals for both channels.
Further explanations are referring to a single channel and apply independently to each
output of the dual channel device. The IC allows user-specific adjustments of angular
range, zero angle, and clamping voltages. The settings are stored permanently in a
non-volatile memory (NVM). The programmable angle sensors are pre-programmed,
pre-calibrated and therefore, ready to use.
