A reduced power analog-to-digital (A/D) converter is disclosed herein. Reference current to an op-amp used in an A/D converter is reduced during later conversion cycles in an A/D conversion process. The reference current to the op-amp can be reduced without sacrificing overall accuracy of the output of the analog-to-digital converter, even though reducing the current to the op-amp reduces the accuracy of the op-amp. This is possible because the op-amp only needs to operate at maximum accuracy during the first conversion cycle, and can operate at reduced levels of accuracy during later conversion cycles.
