Abstract:
1. A control unit for a transportation device having a processing unit that is supplied with power by a first supply voltage and has a signal converter for converting analog signals to digital signals; the signal converter having an analog converter stage for generating a modified signal from an analog signal which is present at the signal converter input, and a digital converter stage for generating a digital signal from the modified signal; the analog converter stage having a signal integration unit whose output signals are fed to a signal amplitude comparator; and the digital converter stage having a scanning device to whose output the analog-to-digital-converted digital signal is applied; wherein, the digital converter stage comprises configurable logic circuits provided on a chip of the processing unit; the analog converter stage comprises components outside the processing unit; and the analog converter stage is supplied with voltage by a second supply voltage having a voltage that differs from the first supply voltage.
