Abstract

A device for evaluating a magnetic field with an integrated circuit with a magnetic field sensor is provided, which has a first connection, a second connection, and a third connection led out from the housing. A signal conditioning circuit is connected to the magnetic field sensor. A control circuit generates a control signal for controlling the signal conditioning circuit based on a detected transmission signal with a detection circuit for detecting the transmission signal. The signal conditioning circuit generates an analog signal based on a sensor signal and based on the control signal. An evaluation circuit evaluates the analog signal and compares the analog signal to a default value to adjust the signal conditioning circuit via the digital transmission signal such that the analog signal corresponds to the default value.
