Abstract
A circuit configuration for detecting a functional disturbance has a first and a second differential amplifier. The outputs of the differential amplifiers are connected to the inputs of a gate. One input of the differential amplifiers is in each case connected to a reference potential terminal. The respective other input of the first and second differential amplifiers is connected to a monitoring means, which responds in the event of a change in the supply voltage at a supply potential terminal of the circuit configuration.
