Pin no 8 is segregated as NC which means it is not supposed to be connected anywhere. Specific circuit configurations are there to make standard null offset adjustments. The input offset voltages of OP-AMPs come into action due to the mismatches caused by collector currents, collector gains, collector and emitter resistors.
But this mismatch can be removed by making use of offset adjustment pins. LM741 can be used for the construction of: In addition, a potentiometer/ variable resistor is connected between the pins 1 and 5 to fine-tune the circuit. In conclusion, you will see this op-amp in many electronics projects. Unity Gain Amplifier ExampleĪs we see earlier, one of the uses of OP-AMP is unity gain amplifier or buffer amplifier. The follower provides a gain of one with output exactly the same as the input. On the other hand, the inverter reverses the polarity of input in addition to unity gain provision. The output resistance of Op-AMP is quite negligible. Hence, this circuit offers as much current according to the requirement of the load. This diagram shows a circuit of the noninverting unity gain amplifier. In this case, input will be equal to output. In this circuit, we give an input voltage of 6 volts. After that, we connect a feedback resistor. Because the gain of the amplifier is unity. Vout = 6 x 1 = 6 volts // Because gain=1 and Vin=6 volts According to this equation: Vout = Vin x Gain As a result, the output shows 6 volts on the oscilloscope. This square wave generator converts an AC sine wave into a square wave. But we can also call it a zero-crossing detection circuit. In short, its main function is to produce a square wave from a sine wave. In this example, LM741 acts as a comparator. It compares the voltage magnitude of zero voltage reference and sine wave. Whenever a sine wave passes zero voltage level, we will get a square wave at the output. The comparator produces +15 and -15 volts output. In short, the real-life applications of LM741 are: This edge detection circuit converts op-amp output into a square wave. This picture shows a 2D physical diagram of a DIP package.
