![]() ![]() If the voltage at Pin2 is greater than the voltage at Pin3, i.e., the voltage at inverting input is higher, the output signal stays low. Pin2 is the inverting input and Pin3 is the non-inverting input. Pin2 & Pin3 (Input): These are input pins for the IC.Similarly, if the output is said to be low, it means that voltage at the output is equal to negative supply voltage. If the output is said to be high, it means that voltage at the output is equal to positive supply voltage. The voltage at this pin depends on the signals at the input pins and the feedback mechanism used. Pin6 (Output): This is the output pin of IC 741.The voltage between these two pins can be anywhere between 5V and 18V. The 741 IC draws in power for its operation from these pins. Pin4 & Pin7 (Power Supply): Pin7 is the positive voltage supply terminal and Pin4 is the negative voltage supply terminal.Now let’s take a look at the functions of different pins of 741 IC: The below figure illustrates the pin configurations and internal block diagram of IC 741 in 8 pin DIP and TO5-8 metal can package. Pinout of IC 741 Op Amp and their Functions We couldn’t find the information on the manufacturer of the second TO5-8 Metal can package IC. NOTE: The manufacturer of the first IC in the above picture in 8-pin DIP Package is STMicroelectronics and that of the third IC in 8-pin SOIC format is Texas Instruments. This Op-amp IC comes in the following form factors: It also features short circuit protection and internal frequency compensation circuits built in it. IC 741 Op Amp can provide high voltage gain and can be operated over a wide range of voltages, which makes it the best choice for use in integrators, summing amplifiers and general feedback applications. The number 741 indicates that this operational amplifier IC has 7 functional pins, 4 pins capable of taking input and 1 output pin. It was first manufactured by Fairchild semiconductors in the year 1963. The 741 Op Amp IC is a monolithic integrated circuit, comprising of a general purpose Operational Amplifier. In this article we will take a look at one of the most used Op-Amp ICs: IC 741 Op Amp.įor learning more about Op-Amps, visit this page: Operational Amplifier Basics IC 741 Op Amp (Operational Amplifier) Op-Amp ICs have become an integral part of almost all analogue circuitry. It has a very high voltage gain, typically of the order of 10 5 (100dB).Īlthough they are initially designed for performing mathematical operations like addition, subtraction, integration, differentiation etc., (hence the name Operational Amplifiers), by using external components like resistors and capacitors to create a required feedback mechanism, it can also be used as an amplifier and for many other functions like filters, comparators etc. Non-Inverting Amplifier Circuit Using 741 Op AmpĪn operational amplifier, also called as an op-amp or op amp, is an integrated circuit primarily designed for performing analogue computations.Inverting Amplifier Circuit Using 741 Op Amp.Pinout of IC 741 Op Amp and their Functions.I have compiled a list of my favourite compatible ICs that are readily available and affordable, but please note that it is not an exhaustive list and there may be many more. If you were using an op-amp for simple educational experiments to calculate the gain, or perhaps for simple basic circuits, then many cheaper equivalents would perform just as effectively, and save you money. ![]() Many manufacturers have made minor changes to the original design, however for the most part they are pinout equivalents, and the same formula for gain calculation applies. However, you can make your budget stretch further if you look for cheaper equivalents.Īlmost all the modern 8-pin operational amplifiers take their architecture from the earlier 741 chip. The 741 is the one everyone thinks of when looking for a general-purpose amplifier, however, if you rely too much on the same chip and seller, then they will sometimes artificially hike up their prices. Some chips have been getting expensive due to students relying too much on one model and manufacturer. There are many 741 compatible chips readily obtainable however, the problem is that many students and colleges are not aware of the different manufacturers and the model numbers. ![]()
