Beschreibung
Zusammenfassung:	With respect to particularly accurate measurements even at changing temperatures with structurally simple means, an integrated circuit (5) for signal processing of a sensor (2), wherein the sensor (2) is an inductively working sensor (2) or a eddy current sensor (2) and wherein the circuit (5) has electronic components and is part of an oscillating circuit, is characterised by a temperature-control device for the open- or closed-loop controlling of a temperature and/or of a temperature distribution in the circuit (5) and/or in at least one electronic component of the circuit (5). Furthermore, a method is specified for the open- or closed-loop controlling of a temperature or of a temperature distribution in the circuit (5) or in at least one electronic component of the circuit (5), wherein recorded temperature measurement values are compared to a specified target value for the temperature and wherein in the event of an deviation from the target value, the temperature or temperature distribution is controlled in an open- or closed-loop manner towards the target value.
