Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. I usually lv351n to datasheet sites but looking for LF in Google links to its datasheet that shows its pin numbers and a picture of its layout.

Did I mention you need to look at the datasheet. Anyone know what pins I should use?


I was given this circuit and there is a lf ic chip that is shown as a triangle, I’m not sure how to use the chip or what’s connected to where, Dahasheet was never taught how to read this type of schematic. I don’t know if other similar opamps like the TL will overload the same. Media New media New comments Search media.


The data sheet has all the information that you require. Thread starter grendal Start date May 6, So I guess what I am saying is look at the datasheet, then come back with more questions. dataxheet

Not sure if it works not yet built it, so I’d want something with a low overload I think the circuit is supposed to give a hum when a nearby cell phone is ringing? Welcome to our site!

Then it uses the strong UHF or microwave signal transmitted to overload the input of the opamp. By continuing to use this site, you are consenting to our use of cookies.

In much the same way that logic circuits are designed, modern CAD packages automatically hook the power supply pins to the appropriate voltages. Ordinary opamps cannot drive low impedance headphones. Datasheets, Manuals or Parts.

The schematics I’m familiar with for ics are like this one. Click here to register now. Articles Top Articles Dahasheet resources.

Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at It is a level of detail that is not needed once you look at the datasheet.

I have the pin out but I guess what I’m trying to ask is what pins in the schematic are in use? The pin numbers assigned to the output, the non-inverting input marked with a plus sign, and the non-inverting input marked with a minus sign are unabiguous.

The pinout is in the datasheet. The LF opamp is old and is not made anymore.
