In the same way, when the voltage value at pin 3 >> pin 2 which means that non- inverting input has a high value of voltage, then the output signal is high. PARTS LIST OF MICROPHONE AMPLIFIER USING OPEARTIONAL AMPLIFIER 741. Pin diagram and Circuit of Op-Amp IC 741; Easy way to understand what is logic gate? Pin number 1 is the Offset Null. Updated May 9, 2018. The equivalent for UA741 IC are LM4871, AD620, IC6283, TL081, LF351N. A typical IC 741 is constructed with a circuit that is included with 11 resistors and 20 transistors. Power supply: For the functionality of this operational amplifier, it requires a minimum voltage of 5V and it can handle up to 18V. When the voltage is given to the pin3 then we can get the output from the pin-6. It is used in regulated power supply. When the voltage value at pin 2 >> pin 3 which means that inverting input has a high value of voltage, then the output signal is low. You may already know that SE/NE 555 is a Timer IC introduced by Signetics Corporation in 1970’s. Internal Structure of 741 op-amp. THE 741 IS USED IN TWO WAYS : 1. Also, the other mirror circuit which is the third one formed by Q10 and Q11 functions as an increased impedance connection between the -ve supply and input.
