Question

- In 741 point out pin-out configuration for inverting input and non-inverting input respectively from the following
A) 2,3,6
B) 3,6,2
C) 2,6,3
D) 3,2,6

Answer 1

Hint: IC $741$ Operational Amplifier. The IC $741$ operational amplifier looks like a small chip. The representation of $741$ IC op-amp comprises eight pins. The most significant pins are 2,3 and 6, where pin $2$ and $3$ are pin $2$ and $3$ denote inverting and non-inverting terminals and pin$6$denotes output voltage. The input is given to the invert terminal of the amplifier. We have negative feedback output that is given to each invert amplifier.

Complete step by step solution:
An inverting amplifier leg two is the input and the output is always reversed or inverted.
IC operational amplifier, The IC operational amplifier looks like small chips. The representation of IC operational amplifier comprises eight pins. The most significant pins are $2,3$ and $6$ where Pin $2$ and $3$ are denote inverting $8$ non-inverting terminal and pin $6$ denotes output voltage.
The input is given to the invert terminal of the amplifier ; we have negative feedback output and is given each to the invert amplifier.

So, the correct answer is “Option A”.

Additional Information:
An \[ideal\] or perfect operational amplifier is a device with certain special characteristics such as infinite open loop gain, infinite input resistance, Zero output resistance, infinite bandwidth and zero offset. It is fundamentally a voltage amplifying device used with external feedback components such as resistors and capacitors between its output and input terminals, an operational amplifier is basically a three-terminal device consisting of two high impedance inputs, one called the inverting input $( - )$ and the other one called the non – inverting input $( + )$. The third terminal represents the operational amplifiers output port which can both sink and source either a voltage or a current

Note:
If we make the connection in such a way that the non- inverting pin is having a high voltage compared to the inverting pin the output will be positive. Current always flows from higher potential to lower potential.
Operational amplifiers are used extensively in signal conditioning or perform mathematical operations as they are nearly ideal per DC amplification.
