I don’t know if other similar opamps like the TL will overload the same. The TL opamp has the same pin numbers. Ordinary opamps cannot drive low impedance headphones.

The schematics I’m familiar with for ics are like this one. Articles Top Articles Search resources. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Then it uses the strong UHF or microwave signal transmitted to overload the input of the opamp.
So I guess what I am saying is look at the datasheet, then come back with more questions. Thread starter grendal Start date May 6, Similar opamps are available.

lf351 pins to 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 think the circuit is supposed to give a hum when a nearby cell phone is ringing? Not sure if it works not yet built it, so I’d want something with a low overload Replacement Transformer Started by ncag Today at 7: Welcome to our site! Did I mention you need to look at the datasheet.
The pinout is in the datasheet.
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.

It is a level of detail that is not needed once you look at the datasheet. To participate you need to 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. You must log in or register to reply here.
