ABSTRACT:
A digital-to-analog converter for high speed applications including slew rate limited waveform generation such as raster scanning is described. The converter includes a binary current ladder for providing a plurality of weighted current values, a plurality of electronic switches, preferably "n"-channel field effect transistors, for directing the current from the binary current ladder to the appropriate output terminals and a gray code controller for controlling the operation of the switches.
