Abstract
An improved digital/analog converter circuit of the analog multiplying type for providing an adjustment for a DC voltage offset. The digital/analog converter circuit generally comprises a code converter, an analog multiplying current source and a bridge output circuit. The code converter converts the values of the tone data into 2's complement numbers. The numbers are then sent into an analog multiplying current source where positive and negative signals are produced to control the current path of a bridge-type output.
