Abstract
A device for ratiometric measurement of voltages for an analog-digital-converter is disclosed. A reference voltage is provided to a microcontroller and a first supply voltage is provided to a first sensor and the microcontroller by a functional providing unit. The first sensor is connected to the microcontroller in terms of signaling by transmitting sensor signals. The microcontroller has a first multiplexer and a second multiplexer. The multiplexers output signals to the analog-digital-converter. The reference voltage and the first supply voltage are present on the input side at the first multiplexer and at the second multiplexer. In a first switching state the first supply voltage can be measured on the output side by using the reference voltage as a reference for the analog-digital-converter. In a second switching state the reference voltage can be measured by using the first supply voltage as a reference for the analog-digital-converter.
