WebWhen the output of the comparator is off the voltage at the PLUS input will be the same as the supply voltage. With the PLUS input voltage higher than the MINUS input voltage the output will remain off. 1. When the SET button is pushed the voltage at the PLUS input will go to zero and the output will turn on. 2. WebGenerally, a comparator compares supply voltage and current measurement to determine the biggest. As a result, the voltages or currents are the input signals of the comparator. Once all inputs align, the comparator electronic circuit compares the two and outputs. Subsequently, the output is either 1 or 0. To begin with,1 indicates the voltage ...
