Abstract

The present invention relates to an autocalibrating analog-to-digital converter and a sensor device comprising such a converter. The analog-to-digital converter comprises a first analog-to-digital converter of the type measured-value-to-pulse-amount converter and a second analog-to-digital converter, which converts the residual value of the first converter at the end of the period to a digital value while using reference values, and an adder, which adds the residual value to the output signal from the first converter. Functions or components of the second analog-to-digital converter are automatically calibrated by means of calibration values measured by the analog-to-digital converter involved, comprising the first and the second analog-to-digital converter, and another example of an analog-to-digital converter of the same composition.
