ABSTRACT:
An analog-to-digital converter circuit having an interface and control logic for access and control by a computer processor. The converter has a total of eleven analog voltages coupled to its inputs, three of which are selectable by the computer processor each time the converter is activated. The remaining eight analog voltages may be addressably selected by the computer processor, to enable any single analog voltage to be converted and transferred to the processor during each conversion cycle.
