A method and a device are for converting a digital input signal to an analog output signal, for example in vehicle safety systems. In the method, a first and a second pulse-width modulated signal is used for generating a first and a second analog intermediate signal. The second intermediate signal is converted to a third intermediate signal, wherein this conversion is controlled by a third pulse-width modulated signal. A fourth analog intermediate signal is generated from the third intermediate signal. The analog output signal is then generated from the first intermediate signal and the fourth intermediate signal. The first, second and/or third pulse-width modulated signal is preferably but not necessarily derived from the same digital input signal.
