Abstract
A sensor interface circuit comprises an input arranged to receive a sensor signal being an electrical signal representative of an electrical quantity. The electrical quantity includes a physical quantity converted in a sensor. The sensor interface circuit includes conversion means arranged for converting the sensor signal into a digital signal, memory to store sensor characterisation data, signal processing means adapted to obtain a first sensor result by processing the digital signal using the sensor characterisation data, and an output unit arranged to receive and output the first sensor result, the digital signal and the sensor characterisation data.
