Analogue voltage programming

Abstract

An analog circuit arrangement (1) to variably set a voltage Uout, within defined voltage limits, has a non-inverting adder (10) with a positive input (11). A voltage divider (20), with at least a first stage (21) and a second stage (22), is connected to the positive input (11) of the adder (10). At least one stage has a parallel circuit of n resistors (R1, R2, . . . , Rn) that are each connected in series in a conduction path (L1, L2, . . . , Ln) to an overcurrent protection device (F1, F2, . . . , Fn). At least one device (30) actively changes one or more of the overcurrent protection devices (F1, F2, . . . , Fn) into a state that interrupts the respective affected conduction path (L1, L2, . . . , Ln).
