The paper presents a method for digital adjustment of the analog-to-digital converter transfer function. A converter with such adjustments is a useful tool for correcting non-linearity of transducers, especially those with high linearity, in case of which the numerical correction would lead to loss of resolution.An implementation of such a converter to adjust a carbon monoxide sensor transducer has been presented.
