The coreless open-loop sensors are based on precise and stable Hall technology. Thus the output signal is highly linear over temperature and lifetime. Due to lack of an iron core the sensor signal shows neither hysteresis nor does it suffer from saturation. Due to the integrated current rail there is no need for external calibration. The differential measurement with two Hall cells ensures high accuracy even in a noisy environment with cross-talk from adjacent current lines or magnetic stray fields.
