Abstract

The increasing utilization of digital data acquisition systems has resulted in the design and development of a large number of different analog-to-digital voltage converters. Each of these designs exhibits varying specifications with regard to accuracy, speed, environmental tolerance, reliability, and cost.

These specifications are usually interrelated and the nature of the interrelations are, in turn, related to the design approach.

As an example of these interrelations, one could consider the specifications of a converter designed around an electro-optical approach requiring a cathode ray tube with coding mask. In this approach, the analog input voltage causes the deflection of a swept beam in a cathode-ray tube. The luminous spot is viewed by a photocell through a suitably coded aperature plate such that the output of the photocell represents a serial binary number that is directly proportional to the analog input. A converter designed around this approach can readily display excellent specifications with regard to speed.
