Abstract

A device for conditioning the output signal (V2OUT) of an analog transducer (1), includes an energizing section (F2) and a detecting section (D2) with a comparator (COMP), a synchronous memory (FF), a timer (T), and a low pass filter (R,C).A digital output signal (VQ) - that is available at an output terminal (TO) and is controlled by the synchronous memory - and an analog output signal (VO) - that is provided by the low pass filter - are indicative of the amplitude of the transducer output signal. The synchronous memory is controlled by the comparator on the basis of a comparison between the transducer signal and an analog signal at the output terminal, the latter being provided through a feedback ring.
