Abstract
An integrated amplifier circuit includes an operational amplifier, a signal input terminal connected to the non-inverting signal input of the operational amplifier, a signal output terminal connected to the signal output of the operational amplifier, a first supply terminal at supply potential, a second supply terminal connected to reference potential, the first and second supply terminals being connected to internal terminals of the operational amplifier to be acted upon by the supply and reference potentials, a first ohmic voltage divider connected between the signal output of the operational amplifier and reference potential, an ohmic resistor connected between the divider point of the first voltage divider and the inverting signal input of the operational amplifier for obtaining a real negative feedback, a second ohmic voltage divider connected between the first supply terminal and reference potential, a supply resistor connected between the divider point of the second voltage divider and the non-inverting signal input of the operational amplifier and a third supply terminal associated with the output stage of the operational amplifier, the third supply terminal being connected…
