摘要

PROBLEM TO BE SOLVED: To provide a trim DAC circuit for adjusting the output of a digital-to-analog converter (DAC).;SOLUTION: The trim DAC may be used to adjust a plurality of resistor segments in the DAC. The trim DAC 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.;COPYRIGHT: (C)2008,JPO&INPIT
