Part Number:LM211
The LM211 application I have uses a single +23.5Vdc bias voltage applied to VCC+ of the LM211 comparator with the VCC- pin grounded. For one state of the comparator, the IN+ pin of the comparator will be at 13.4Vdc and the IN- pin of the comparator will be at 0volts. The voltage at the IN- pin will therefore violate the common mode input voltage requirement of being 0.5volts above the VCC- pin. I have seen threads which say that the LM211 comparator output will be in the correct state as long as one of the inputs is within the required common-mode input voltage range. So will the LM211 comparator output function properly with 0volts applied to the IN- pin, or should I make a design change to keep the IN- pin 0.5V above the VCC- pin?
