A two-stage operational amplifier has an input stage and a downstream output stage. In this configuration, the magnitude of a first supply potential which supplies the input stage and is provided by a device for voltage reduction is smaller than that of a second supply potential which supplies the output stage. With a small chip area, as a result of predominantly being able to use standard MOS components, and with a low power requirement, high output voltages are possible at the output of the operational amplifier.
