Abstract
A circuit for ensuring a complete saturation of both operational amplifiers of a single-input bridge amplifier is provided. A voltage divider is connected between the inverting inputs of the two amplifiers and a saturation current signal is injected on the intermediate node of the voltage divider. Such a saturation current signal is obtained through dedicated sensing devices of the state of saturation reached by the transistors of the output stages of both amplifiers of the single-input bridge amplifier.
