A current sensor chip and systems and methods for calibrating thereof are provided. The current sensor chip includes a first magnetic field sensor element configured to generate a first analog sensor signal representing a magnetic field caused by a primary current passing through an external primary conductor, an analog-to-digital converter coupled to the first magnetic field sensor element and configured to generate a digital sensor signal based on the first analog sensor signal, a digital signal processor coupled to the analog-to-digital converter to receive the digital sensor signal and configured to determine, based on the digital sensor signal and based on calibration parameters stored in memory, a corresponding current measurement signal that represents the primary current, and an external output pin coupled to the first magnetic field sensor element to receive the first analog sensor signal or an analog signal derived therefrom by analog signal processing.
