Résumé en anglais

One of the usual features that an operational amplifier may offer is the rail-to-rail capability. This means that its output range is equal to the power voltages (positive and negative or zero) without any offset. In some cases this feature does not concern with the performance of the system because it does not operate in the limits of the output range or the offsets are small enough not to care about them. Nevertheless, when an accurate instrumentation system must be used, as in this article, the rail-to-rail capability is crucial not to degrade the performance. For instance, the circuit may loose linearity and resolution if the operational amplifiers are not adequate. In our case, a circuit to perform some discrete time control algorithms needed a maximum output range for the system to work properly. With the initial operational amplifiers, the performance was not adequate. After setting rail-to-rail ones the problem has been resolved.< Réduire
