Abstract
A digital to analog converter, wherein a time/voltage array is programmable, to determine which of the possible reference voltages will be enabled by which of the control inputs. Anther set of programmable options, in an output connection matrix, determines which of the internal voltage lines will be connected to which output lines. After the output connection matrix, output selection logic is used to determined which class of output levels are to be used. The output selection logic also preferably includes polarity-reversal gates, so that the polarity of a bipolar output can be reversed.
