A capacitive digital to analog converter which can be trimmed to obtain precise capacitor matching is provided. The trimming method may be utilized with a weighted capacitive D/A converter having a scaling capacitor and an ordered plurality of capacitors for developing an analog output signal as a function of a digital input code. A compensation portion is coupled to at least a predetermined one of the capacitors for selectively changing the effective capacitive value of the predetermined capacitor.
