Abstract
A digital to analog converter with bit circuits arranged in binary order, in which a supplemental current circuit is added to selected bit circuits to enable convenient and efficient conversion from binary to BCD operation. Supplemental BCD currents are controlled by a bias circuit which automatically increases the BCD bit circuit bias to a level at which the full-scale BCD output current is substantially equal to the full-scale binary output current.
