Abstract
In a device for the reading of a set of resistive elements (1.0, . . . , 1.n) in which an interrogation potential (V.sub.0) is applied at each instant to an element while a reference potential (v) is applied to the other elements, a stabilization circuit (CS) operates to keep the reading ports (L.0, . . . , L.n) at the reference potential. The present invention may find particular application to the reading of the elementary magnetoresistive heads of a magnetic reading head.
