Abstract

A bipolar digital to analog converter having a pair of identically configured digital to analog networks, the outputs of which are summed. The input of these networks are connected by an appropriate control circuit which, depending upon whether the digital data is negative or positive, directs the data to one or the other of the networks, to progressively turn that network "on" or "off", depending upon whether the data is increasing or decreasing in its relative value, and biases the network not receiving the data either completely "off" or completely "on".
