Abstract
In a method of compensating for the tolerance errors in a digital-to-analog converter (D/A) the tolerance errors of the D/A are measured and individual correction factors are provided for each of the errors. The correction factors are stored and one of them is arithmetically combined with a portion of the digital number being converted to produce a combined signal. The combined signal is input into the digital-to-analog converter to produce an analog signal accurately representative of the digital signal.
