The KMA220 is a dual channel magnetic angle sensor module. The MagnetoResistive (MR) sensor bridges, the mixed signal Integrated Circuits (ICs) and the required capacitors are integrated into a single package. Both integrated channels are working full independently. The supply voltage has common terminals. Further explanations are referring to a single channel of the KMA220.
The NXP KMA220 is a dual channel magnetic angle sensor module designed for high-precision angular measurement. It integrates MagnetoResistive (MR) sensor bridges, mixed signal Integrated Circuits (ICs), and required capacitors into a single package. Both integrated channels operate fully independently, sharing a common supply voltage. The module is pre-programmed and pre-calibrated, ready for immediate use without external components.
The device allows for user-specific adjustments of the angular range, zero angle, and clamping voltages for each channel separately, with settings stored permanently in non-volatile memory. Key features include a high temperature range up to 160 °C, overvoltage protection up to 16 V, and fail-safe non-volatile memory with write protection using a lock bit. Each channel includes a user-programmable 32-bit identifier and supports independent programming via One-Wire Interfaces (OW).

Yes, the module is pre-programmed, pre-calibrated, and ready to use without external components.
Settings for angular range, zero angle, and clamping voltages are stored permanently in non-volatile memory.
The sensor can raise a diagnostic condition and switch the output into diagnostic mode if magnet-loss detection is enabled.
