ABSTRACT:
A digital logic buffer device for generating dual polarity analog signals is described. In the presently preferred embodiment, buffer receives the positive polarity analog output of a digital-to-analog converter (V.sub.DAC), and a sign bit. If the sign bit indicates that a positive polarity is required, the buffer will output approximately V.sub.DAC. If a negative polarity is required, aproximately -V.sub.DAC will be generated.
