Abstract
A circuit configuration for digitally setting analog parameters includes at least two analog multiplying devices each having a differential amplifier stage. The differential amplifier stages have differential inputs connected in parallel with one another and driven by an analog bipolar input signal. The differential amplifier stages have outputs coupled to one another cumulatively. The differential amplifier stages receive supply currents which are to be switched on and off individually as a function of a corresponding digital control signal and are graded using binary code.
