And if the voltage of inverting input (-) is Higher than non-inverting end (+), then output is LOW. When voltage at non-inverting input (+) is higher than the voltage at inverting input (-), then the output of comparator is HIGH. Like if PIN 3 is having +ve polarity then we will get +ve polarity of output from PIN 6. When input source is connected to non-inverting terminal PIN 3 and PIN 2 is feedback with the output PIN 6 then the op-amp is in non-inverting condition. Like if PIN 2 is having +ve polarity then we will get –ve polarity of output from PIN 6. When input source is connected to inverting terminal PIN 2 and feedback with the output PIN 6 then the op-amp is in inverting condition. OUTPUT Voltage = Gain * Input VoltageĪn op-amp can be used in two ways: 1. The LM741 can operate with a single or dual power supply voltage. Op-amps have large gain and usually used as Voltage Amplifier. The main function of this IC is to do mathematical operation in various circuits. An operational amplifier IC is used as a comparator which compares the two signal, the inverting and non-inverting signal. LM741A, LM741C, LM709C, LM201, MC1439, and LM748Īn LM741 operational amplifier is a DC-coupled high gain electronic voltage amplifier.
