Question

Find the pin configuration of µA741operational amplifier?

I had been asked this question in an interview for job.

I'd like to ask this question from Integrated Circuit Package Type, Pin Configuration and Temperature Range topic in portion Operational Amplifier Characteristics of Linear Integrated Circuits

Answer 1

The pin configuration of the µA741 operational amplifier is as follows:

1. Offset Null: Used to adjust the input offset voltage.
2. Inverting Input (-): The input terminal where the inverting signal is applied.
3. Non-Inverting Input (+): The input terminal where the non-inverting signal is applied.
4. V- (Negative Voltage Supply): The negative supply voltage for the op-amp.
5. Offset Null: Used for adjusting the input offset voltage (connected internally to the same point as pin 1).
6. Output: The output of the op-amp where the amplified signal is obtained.
7. V+ (Positive Voltage Supply): The positive supply voltage for the op-amp.
8. NC (No Connection): This pin is not connected to any internal circuit and is typically unused.
9. Offset Null: Another offset adjustment pin for fine-tuning the input offset voltage.

So, the µA741 op-amp is a 8-pin IC with the following configuration (starting from pin 1 and going clockwise):

1. Offset Null
2. Inverting Input
3. Non-Inverting Input
4. V-
5. Offset Null
6. Output
7. V+
8. NC (No Connection)

This is the standard pinout for the µA741 op-amp in an 8-pin Dual In-line Package (DIP).
