Abstract (en)
[origin: WO2006045399A1] An operating device for an illuminating means, particularly an electronic ballast for gas discharge lamps, comprises a regulating and/or control unit to which operating parameter signals can be supplied, which are converted by an analog-to-digital converter. At least one property of the analog-to-digital converter can be set according to the actual operating state of the illuminating means for adaptation to the operating parameter signals.
