WebJul 14, 2024 · Here is a step-by-step process: First the circuit without any errors. Apply a 9-volt power supply to the circuit. Rotate or adjust a VR1-potentiometer in the breadboard to set a reference voltage to pin 3 (read digital multimeter in left is 2-volts). Apply an input voltage to the INPUT at pin 2 of IC1 (Read voltage as Zero). WebDec 13, 2024 · Many comparators have open-collector outputs so you can parallel them. This is useful in window-comparator applications. This means that when the inverting terminal voltage is greater, the load connected to output can be powered on. If V- > V+ then the output pulls low. A load connected between V CC and the output will turn on.
