A trimdac circuit for adjusting the output of a digital-to-analog converter (DAC) is provided. The trimdac may be used to adjust a plurality of resistor segments in the DAC. The trimdac may include a programmable Read Only Memory (ROM) or other suitable memory device. The ROM may include a plurality of multi-bit digital words. Each of the multi-bit digital words may control a plurality, and most preferably a pair of variable resistance circuits. Each of the pair of variable resistance circuits may adjust a resistor segment of the DAC.
