METHODE ZUR BESTIMMUNG EINER UNBEKANNTEN SPANNUNG UND DUAL-SLOPE AD-WANDLER.

摘要

A dual slope analog-to-digital converter with automatic short cycle range determination. The time period of the signal integrate phase is adjusted to accommodate different ranges of input signals. Range selection is achieved automatically with the converter switching quickly from one range to another until the right range is found, without the necessity of displaying an "out of range" reading. Normal mode rejection of 60 Hz noise is achieved on all timing ranges.
