WebThe Analog input module senses up to 16 single-ended or 8 differential analog inputs and converts them to a proportional four-digit BCD or twelve-bit binary value. You can select from five voltage or three current input ranges. Each input can be configured as a current or voltage input with internal jumpers. Webfier input, which is not necessarily greater than the supply-voltage range. When the common-mode voltage exceeds the linear operating region, one of the transistors in the input stage is not biased properly and causes the output voltage to invert. Figure 2 displays the input and output voltage of an amplifier that suffers from phase inversion.
