Datasheets, Manuals or Parts. So I guess what I am saying is look at the datasheet, then come back with more questions. Anyone know what pins I should 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.

Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register. I usually go to datasheet sites but looking for LF in Google links to its datasheet that shows its pin numbers and a picture of its layout. Forums New posts Search forums. Not sure if it works not yet built it, so I’d want something with a low overload Potentiometer Questions Started by norbss Yesterday at It is a level of detail that is not needed once you look at the datasheet.


Then it uses the strong UHF or microwave signal transmitted to overload the input of the opamp. I have the pin out but I guess what I’m trying to ask is what pins in the schematic are in use?

Similar opamps are available. Did I mention you need to look at the datasheet.

Papabravo Well-Known Member May 6, Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. I don’t know if other similar opamps like the TL will overload the same.

To participate you need to register. In much the same way that logic circuits are designed, modern CAD packages automatically hook the power supply pins to the appropriate voltages.

lf351 pins to use?

Ordinary opamps cannot drive low impedance headphones. By continuing to use this site, you are consenting to our use of cookies. 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, I was never taught how to read this type of schematic.

The LF opamp is old and is not made anymore.
