Abstract

A transducer device for converting an analog DC voltage signal into a digital signal is provided, with an oscillator device for outputting a first oscillator signal and a second oscillator signal, whereby the oscillator device is formed to generate the first oscillator signal and the second oscillator signal phase-locked to one another and with the substantially same frequency from a reference signal, with an analog frequency converter connected to the oscillator device for transforming the analog DC voltage signal by the first oscillator signal in a first spectral range with a first center frequency to obtain a transformed signal, with an analog-to-digital converter for converting the transformed signal into a transformed digital signal; and with a digital frequency converter connected to the oscillator device for transforming the transformed digital signal by means of the second oscillator signal in a second spectral range with a second center frequency to obtain the digital signal.
