Otherwise, just about any FET input op amp will do as a sub. Mar 1, 0. Hard to come up with a sub without knowing what the was doing. Op-Amps are known for its high input impedance, meaning it will not draw any current or disturb the signal that is being given to the Input pin.

Linear Caa3140 website is also quite helpful in that regards. These two pins can be used to correct the offset error of an Op-Amp.

replacement for CA3140 Op-Amp

You might indicate what characteristic of a 25 year old op amp is significant for a better suggestion. In addition to beenthere’s suggestion, Mouser’s search engine will help you to find op amps that have properties that are similar.

Also remember that a saturated Op-Amp will comparatively draw more current and thus results in power loss. I am working on a project which requires a CA Op-Amp but I can’t get one from my area so could you please suggest any other types of Op-Amp which can convieniently be used in place of the CA Op-Amp. If you know what that is, you can go to sites and search by parameters.

Other than that one notable unique feature of the UA Op-Amp is that it has two Offset pins pin1 and pin 5. The input stage of an Op-Amp is mostly complex since it involves many stages.


An Introduction to Motion Sensors: Mar 19, 2. It’s a direct replacement for so many that replace the could work LM,http: Also the difference between the voltage values of the Inverting and the Non-Inverting pin should not be more than the Differential Input Voltage Rating. Mar 19, 1.

The UA is not a rail to rail Op-Amp hence the output voltage will not reach the maximum positive or maximum negative voltage when saturated. Apr 20, 15, This Op-Amp can be used for many general purpose applications like, Voltage follower, Buffers, Comparators, Amplifiers, Dahasheet and much more.

No, create an account now. Although there are dozens caa3140 other Op-Amps with advanced technology, the UA still seems to be the first choice for many engineers because of its reliable properties. Do you already have an account? A ordinary old opamp is completely different. Mar 19, 4. And pin 8 is an output strobe. Jc, my password is: If you are curious to learn about few application circuits of this IC then you can read through how LM is used since both the IC shares the same applications.

Op-Amps are known for their very large Open-Loop Gain, but sadly this gain is accompanied by noise hence most of the circuits are designed using Closed-Loop. If the project needs the strobe pin to control the output, then you may be out of datwsheet.

Hi, NTE is a direct replacement. Dec 20, 10, 1, A Negative feedback is commonly preferred, since it has predictable behaviour and stable operation.

The CA is an old Cmos opamp.

Mar 19, 1 0. Quote of the day. That is when the voltage difference between the inverting and no-inverting pins are zero the output voltage of the Op-Amp should also be zero. Mar 20, 7. The Op-Amps as we know are the work horse for most electronics circuit designs.


PIR, Tilt, Force, and More Learn about various movement-type sensors including accelerometers, tilt sensors, vibration sensors, PIR passive infrared sensors, and rotation sensors. Mar 20, 9.

UA Op-amp IC Pinout, Features, Equivalent & Datasheet

Mar 20, 8. If not then it is considered as offset error and it can be brought to zero again by providing a offset voltage through the offset pins that would nullify the error. But every Op-Amp designs will have some common design considerations or tips which are common among them and we will discuss the same further. Sep 2, Jun 30, 3. Mar 19, 6. Jul 17, 22, dataasheet, TL — Programmable Reference Voltage.

Datsheet is a single package Op-Amp that has been widely used by engineers and students for quite a long time now.

IC CA3140 Datasheet

An OP07GP, for instance. The Input common-mode range value must be considered while supplying voltage signals because the input voltage should never exceed the rail voltage else it will create a latch-up condition which in return will create a short circuit of the supply voltage and thus damaging the circuit permanently.

Datashete Devices has an online circuit simulation datsaheet to help you choose a suitable op amp. A Closed-Loop system provides feedback to the input this limiting the gain value of the Op-Amp and the noise associated with it.

The main difference is that LM has two Op-Amps inside package making to more cost effective and compact. There are a plethora of application circuits for Op-Amp each having its characteristics and significance in its own way.
