    ... LM397 Single General Purpose Voltage Comparator General Description The LM397 is a single voltage comparator with an input common mode that includes ground. The LM397 is designed to operate from a single 5V to 30V power supply or a split power supply. Its low supply current is virtually independent of the magnitude of the supply voltage ...

    ... Application Notes (Continued) Input Stage The LM397 has a bipolar input stage. The input common mode voltage range is from – 1.5V). S Output Stage The LM397 has an open collector grounded-emitter NPN output transistor for the output stage. This requires an exter- nal pull-up resistor connected between the positive supply voltage and the output ...
