TLCN is another favourite of mine because it is affordable.
Pin Compatible Equivalent Op Amps
This means you could connect the inputs directly to a signal source with minimal impedance issues. You can get these from RS at very affordable prices. These are ideal for battery powered circuits and portable devices. I have compiled a list of my favourite chips that are readily available and affordable. Mr Vis Education Donate. There are many compatible chips readily obtainable; however, the problem is that many students and colleges are not aware of the different manufacturers and the model numbers.
Your basic op amp circuit configurations will be the same and you will be using the same formulas. Consequently, some chips have been getting expensive due to students relying too much on one model and manufacturer. The CAE is a direct replacement for theand the manufacturers designed it with this being the main purpose.
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. These CMOS operational amplifiers will operate on a voltage as low as 2.
You can pick one of these up from Maplin for around 62p whilst you are on your way to the chip shop. 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.
This is a general-purpose operational amplifier with a JFET input, which is even better because its input impedance will be high.
This is one of my favourites ca3140w it is almost identical to the old in technology. The LM 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.
Both chips are pin identical toexcept the MCP has a chip select on pin 8. Even with all the modern day equivalents, the LMCN is still a very cost effective chip at around 54p each or 32p when you buy from Farnell. It has JFET inputs and is pin compatible with the There is a minor difference in that pin 8 is for the strobe function, which controls the output, however, for basic op amp circuits it is not used.
HARRIS CA3140E BiMOS Operational Amplifier 4.5MHz, Dip-8
CAE is pin equivalent to the LM The common mode input voltage range will go 0. This is useful if you wanted to switch audio signals, otherwise, you could always tie it permanently to ground. You can make your budget stretch further if you look for cheaper equivalents. Obviously, it will be cheaper for bulk purchase. This is a general-purpose amplifier utilising bipolar junction transistor technology. This is the low noise version, ca3140f is extremely useful for high-fidelity audio applications.

Here is a list ca314e the approximate price for one at Farnell. The is the one everyone thinks of when looking for a ca3104e amplifier, however, if you rely too much on the same chip and seller, they will sometimes artificially hike up their prices.
This one is the most affordable I could find from Farnell at just 38p each or 29p when you buy If you required high-speed and precision, and money was no object, then this IC is ideal for precision instrumentation, medical equipment, and professional audio.
Almost all the modern 8-pin operational amplifiers take their architecture from the earlier chip. Texas Instruments have one of the largest ranges of integrated circuits that are pin compatible, with JFET inputs.
However, Farnell have the LFN, which is an cw3140e for 38p.
