An LM741 operational amplifier is a DC-coupled high gain electronic voltage amplifier. It has only one op-amp inside. An operational amplifier IC is used as a comparator which compares the two signal, the inverting and non-inverting signal. The main function of this IC is to do mathematical operation in various circuits. Op-amps have large gain and usually used as Voltage Amplifier. The LM741 can operate with a single or dual power supply voltage.
OUTPUT Voltage = Gain * Input Voltage
