Abstract: A method for linearization of the output of an analog-to-digital converter (ADC) is disclosed, said method comprising the steps of creating an analog ADC input signal (ADC
is ) by combining a substantially constant voltage (V
in ) to be measured with an analog dithering signal (ds), feeding the analog ADC input signal to the ADC for converting it into a sequence of digital signal values, and using the sequence of digital signal values for calculating a single resulting digital value representing the voltage to be measured, wherein the analog dithering signal is arranged so that the analog ADC input signal fed to the ADC causes the output(O
rg )of the ADC to vary over at least 50 %, preferably over at least 70 %, most preferred over at least 80%, of the full output range of the ADC. Furthermore, a temperature sensor (TS) using such method and a heat consumption meter (HCM) comprising such temperature sensors are disclosed.
