Abstract
An illustrative packaged magnetic field sensor includes a power input terminal and a sensor output terminal, both accessible from outside of the package housing. A sensing block is situated in the package housing and electrically coupled to the magnetic field sensing device and the sensor output terminal. An adjustment block is situated in the package housing and coupled to the power input terminal and the sensing block. In some cases, the adjustment block may receive one or more messages that include sensor adjustment information. The one or more messages may be modulated onto the power input signal. The adjustment block may decode the received sensor adjustment information from the messages, and store the decoded adjustment information into a memory. The adjustment block may then adjust the output signal of the sensing block based on the decoded adjustment information.
