Abstract
Circuit arrangement for producing a dual-rail output signal having a signal processing apparatus with two switches, which are driven as a function of an input signal, a first output connected via one of the switches to a signal processing apparatus foot point, which is at a first potential, and a second output connected via the other switch to the foot point. The signal processing apparatus is connected via a switching apparatus to outputs of the circuit arrangement in order to output a dual-rail output signal. The outputs of the switching apparatus are each connected to one or to both inputs of the switching apparatus as a function of a control signal. A potential monitoring apparatus defines the potentials at the outputs of the circuit arrangement when these outputs are not connected via the switching apparatus and the signal processing apparatus to the foot point of the signal processing apparatus.
