Abstract
A high accuracy monolithic digital to analog converter (DAC) which employs an EPROM controlled correction DAC to correct for errors in the output of a primary DAC. The correction DAC empolys a non-binary bit weighting which permits the use of low accuracy components in the fabrication of the correction DAC. The output of the primary DAC is skewed so that the required correction is always in a single direction, thereby eliminating the need for a constant offset generator. Resistors necessary for bipolar operation are included on the chip, thereby eliminating the need for connection of any external resistors to achieve such operation.
