Abstract
An electronic analog-to-digital conversion device includes an analog-to-digital conversion block having a first input for receiving a voltage signal to be converted based on a reference voltage signal provided to a second input, and an input block connected to the first input of the analog-to-digital conversion block. The input block receives an input signal at a first resistive network connected to a second resistive network, which is then connected to a reference potential. The input block also includes an active network connected between an output of the first resistive network and the first input of the analog-to-digital conversion block. The active network has a first input terminal directly connected to the second input of the analog-to-digital conversion block for receiving the same reference voltage signal so that the input voltage signal received at a second input of the active network is processed based on the reference voltage signal.
