Potentiometer Questions Started by norbss Yesterday at The pinout is in the datasheet. The TL opamp has the same pin numbers.

Then it uses the strong UHF or microwave signal dataeheet to overload the input of the opamp. 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.

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 schematics I’m familiar with for ics are like this one.

Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Not sure if it works not yet built it, so I’d want something with a low overload Media New media New comments Search media. Replacement Transformer Started by ncag Today at 7: Datasheets, Manuals or Parts. For a better experience, please enable JavaScript in your browser before proceeding. I don’t know if other similar opamps like the TL will overload the same.

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, I was never taught how to read this type of schematic.

I have the pin out but I guess what I’m trying to ask is what pins in the schematic are in use?

In much the same way that logic circuits are designed, modern CAD packages automatically hook the power supply pins to the appropriate voltages. Similar opamps are available. Forums New posts Search forums. Welcome to our site! I usually go to datasheet sites datssheet looking for LF in Google links to its datasheet ddatasheet shows its pin numbers and a picture of its layout. It is a level of detail that is not needed once you look at the datasheet.


Articles Top Articles Search resources. Ordinary opamps cannot drive low impedance datasheeet. So I guess what I am saying is look at the datasheet, then come back with more questions. The LF opamp is old and is not made anymore. I think the circuit is supposed to give a hum when a nearby cell phone is ringing?
