Apparatus for decreasing effect of transition of more significant bits in D/A converter reference of A/D converter. A pair of D/A converters are connected in tandem to eliminate transition of more significant bits of half scale. Also, three D/A converters are connected in parallel with each being offset from one another so that the effect of bit transition is minimized and occurs at different steps in analog output.
