A supply voltage monitoring apparatus for use in an automotive vehicle, having a circuit comprising, an analogue-to-digital converter having an input receiving an analogue voltage signal and an output outputting a digital signal, and an input stage connecting the input of the ADC to the power supply at a point where the value of the link voltage is to be measured. An input stage comprises a potential divider having an upper resistance R1 and a lower resistance R2, the two resistances R1, R2 connected in series two nodes. A first node provides a connection to the link voltage. A second node provides a connection to ground. A centre tap of a potential divider is connected to the input of the ADC. A switchable lower resistance R3 is connected in series with a switch S between the centre tap and the ground, and a control circuit which is arranged to hold the switch S open when the voltage at the centre tap is below a threshold value and to hold the switch closed when the voltage at the centre tap is above the threshold value.
