ABSTRACT:
According to the present invention, standard analog to digital converter circuitry may be utilized to measure an unknown analog value and to produce a digital value after conversion that automatically contains an offset value with respect to a given measurement range. The digital value produced according to the present invention is not representative of a raw measurement value but rather is representative of a value with respect to a given measurement range; thus, a digital value of 0 may indicate the minimum value of a given measurement range rather than a value of 0 Ohms, 0 volts, or 0 Amps. This may be expressed in equation form where the desired conversion value is represented by:
