This is useful if you wanted to switch audio signals, otherwise, you could always tie it permanently to ground. CAE is pin equivalent to the LM Almost all the modern 8-pin operational amplifiers take their architecture from the earlier chip. Consequently, some chips have been getting expensive due to students relying too cca3140e on one model and manufacturer.
However, Farnell have the LFN, which is an equivalent for da3140e. 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.
You can pick one of these up from Maplin for around 62p whilst you are on your way to the chip shop. You can make your budget stretch further if you look for cheaper equivalents.
These CMOS operational amplifiers will operate on a voltage as low as 2.
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. Texas Instruments have one of the largest ranges of integrated circuits that are pin compatible, caa3140e JFET inputs. Both chips are pin identical toexcept the MCP has a chip select on pin 8.
This is a general-purpose amplifier utilising bipolar junction transistor technology.
I have compiled a list of my favourite chips that are readily available and affordable. The CAE is a direct replacement for theand the manufacturers designed it with ac3140e being the main purpose.
HARRIS CA3140E BiMOS Operational Amplifier 4.5MHz, Dip-8
It has JFET inputs and is pin compatible with the You can get these from RS at very affordable prices. 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. Mr Vis Education Donate.
These are ideal for battery powered circuits and portable devices. This means you could connect the inputs directly to a signal source with minimal impedance issues. Here is a list showing the approximate price for one at Farnell.
There is ca3140f 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. Obviously, ca1340e will be cheaper for bulk purchase. This is the low noise version, which is extremely useful for high-fidelity audio applications.
TLCN is another favourite of mine because it is affordable. Your basic op amp circuit configurations will be the same and you will be using the same formulas. There are many compatible chips readily obtainable; however, the problem is that many students and colleges are not aware of the different manufacturers ca3140f the model numbers.
The common mode input voltage ca1340e will go 0. 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.
Many manufacturers have made minor cx3140e to the original design, cw3140e for the most part they are pinout equivalents, and the same formula for gain calculation applies. The 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.
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 as it is almost identical to the old in technology.
