Abstract
A digital-to-analog converter is provided which converts a series of digital binary numbers into an analog signal having an amplitude proportional to the values of the binary numbers. The disclosed embodiment of this invention includes a segment generator having input terminals coupled to receive the most significant digits of the binary numbers to be converted, wherein the segment generator provides a first signal proportional to the values of the most significant digits of the binary numbers. A step generator is also included which receives the remaining lesser significant digits of the binary number and provides a second signal proportional to the values of these lesser significant digits of the same binary numbers. Additionally, means for combining the first and second signals is provided to form an analog signal proportional to the value of the binary number to be converted.
