![]() ![]() 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. The suffix 'N' plastic DIP package type is used by some manufacturers e.g. Do these last letters N and P mean anything like p type or n type In this context, no. 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. LM741C commercial temperature range LM741. 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. Modern op-amps can be chosen that are rail-to-rail. Input voltage range is typically from -Vs + 2 volt to +Vs - 2 volt. As you can see in the picture above, the LM741 IC has a total of 8 Pins which are clearly labeled. Modern op-amps have power supplies that can be as low as 1.8 volts. LM741 Op amp IC Pinout / Pin configuration. Minimum recommended power supply rails are +/- 10 volts. Some chips have been getting expensive due to students relying too much on one model and manufacturer. There are many good reasons not to use the 1968-vintage LM741:. 8 inputs) and 4 outputs.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. Make sure that you have the LM741 extensions in the required folders. , search the LTSpice main folder for all occurrences of LM741. The LM741 series are general-purpose operational amplifiers which feature improved performance over industry standards like the LM709.
