PROBLEM TO BE SOLVED: To provide an electronic unit capable of absorbing errors of an amplifier. SOLUTION: The electronic unit comprises a recognition means 21a for recognizing a reference amplifying analog signal output from the amplifier 10 as a signal value, by amplifying the predetermined reference analog signal input to the amplifier 10, a deciding means 21b for deciding whether the error has been generated at the reference amplifying analog signal, based on the signal value recognized by the means 21a and predetermined decision information, an offset calculating means 21c for calculating an offset value for eliminating the error of the signal value recognized by the means 21a, in response to the decision result of occurrence of the error of the means 21b, and an offset value storage means 24 for storing the offset value calculated by the means 21c. In this case, the output value output from the amplifier 10 is regulated, based on the offset value stored in the means 24 and processed as in the above manner.
