Both chips are pin identical to 741, except the MCP603 has a chip select on pin 8. The common mode input voltage range will go 0.3 V below ground, making it ideal for single-supply circuits.

These are ideal for battery powered circuits and portable devices. These CMOS operational amplifiers will operate on a voltage as low as 2.7 V, and accept a maximum of 6 V. The MCP601 and MCP603 are by Microchip Technology Inc., and cost approximately 33p and 26p respectively. Even with all the modern day equivalents, the LM741CN is still a very cost effective chip at around 54p each or 32p when you buy 100 from Farnell.Ĭontoh pembukuan toko baju sederhana. These come in two flavours, the 741 and 741 A can operate on split voltage rails of +22 V and -22 V, whilst the LM741C requires +18 V and -18 V. This is a general-purpose amplifier utilising bipolar junction transistor technology. The LM741 is a classic op amp chip and as you can see, it has a very simple and standard layout that is identical to all the chips mentioned on this page.

I have compiled a list of my favourite chips that are readily available and affordable. If you were using an op amp for simple educational experiments to calculate the gain, or perhaps for simple basic op amp 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. Almost all the modern 8-pin operational amplifiers take their architecture from the earlier 741 chip.

You can make your budget stretch further if you look for cheaper equivalents. 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, they will sometimes artificially hike up their prices. Consequently, 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.
