ABSTRACT:
An evaluation circuit for the processing of a received differential signal of an optoelectronic circuit, in particular of a light grid, is disclosed. The evaluation circuit has at least one differential amplifier for the amplification of the received signal. A clamping circuit, by which at least one output of the differential amplifier can be switched to a reference potential, is provided for the suppression of an offset of the differential amplifier. The invention further relates to a corresponding optoelectronic sensor and to a signal processing method.
