Abstract
A digital-to-analog converter (DAC) for converting a multi-bit digital word into a corresponding analog value. The converter divides the digital word into a least significant word portion n.sub.1 and a most significant word portion n.sub.2. The portions overlap in that the weight of the most significant bit (msb) of word portion n.sub.1 is the same as the weight of the least significant bit (lsb) of word portion n.sub.2. The converter detects when the lsb of word portion n.sub.2 changes state, and responsively inverts the state of the msb of word portion n.sub.1. Word portions n.sub.1 and n.sub.2 are then translated into respective analog values which are summed together.
