Identification address configuration circuit and method without use of dedicated address pins

An identification address of a sensor interface device is configured in response to the order of connection of first (DXP1) and second (DXN1) package pins to electrodes of a sensor (Q0). A sensor signal processing circuit (23) has first and second inputs coupled through the first and second pins to the sensor for converting a parameter sensed by the sensor to a different representation. A current is forced through the first pin to produce either a high or low voltage on the first pin depending on the order of connection of the first and second pins to the electrodes of the sensor. A voltage on the first pin is compared with a reference voltage to produce a comparison signal which is mapped to produce the identification address.
