Circuit arrangement and method for sequential classification of a plurality of controllable components

摘要

A circuit arrangement for sequential classification of a plurality of controllable components, to each of which a calibration resistor ( 11 ) is assigned for which the resistance value classifies the component in relation to at least one characteristics, comprises switching means through which each calibration resistor ( 11 ) can be connected individually into a calibration network which is suitable for creation of an electrical calibration voltage ( 14 ) dependent on the value of the calibration resistor ( 11 ). The calibration network comprises a constant current source ( 13 ) and a reference resistor ( 12 ) connected in parallel to this via which the output voltage ( 14 ) can be tapped off and can be connected in parallel in each case via the switching means to a calibration resistance ( 11 ).
