ABSTRACT:
The invention is directed to a circuit for conditioning the output signal of a measuring sensor for further processing in a control apparatus which has a fixed ground potential which does not necessarily correspond to the ground potential of the measuring sensor. A conditioning circuit is provided which can be integrated on a chip and has the following characteristics. The conditioning circuit compensates for the fluctuating ground offset between exhaust gas probe and control apparatus ground when utilizing an exhaust gas probe burdened with a potential. The circuit arrangement includes an external circuit which can be changed to influence the input signal to the conditioning circuit. With this changeable external circuit, the output signal of the circuit arrangement can be so modified that the control apparatus outputs an output voltage with offset and an output voltage without offset. In the case of the external circuit for an output voltage without offset, an offset is impressed upon the input voltage which is then again subtracted at the output with an amplification factor so that the absolute value of the impressed offset has no influence on the output voltage.
