Abstract: The present invention describes an apparatus for the conversion of a digital input signal (Sx) into a required analogic output signal (Idac). The apparatus comprises first circuit means (1, 5) having said digital input signal (Sx) that is representative of the required output signal (Idac) and suitable for producing a first signal (Imain) on an output line (2) and second circuit means (3, 20) suitable for supplying a second signal (Itrim) on said output line (2) in reply to a further digital signal (Dult). The further digital signal (Dult) is function of external variables (Var) and the union of said first (Imain) and said second (Itrim) signal on said output line (2) forms the required analogic output signal (Idac).
