LFN Datasheet(PDF) – Fairchild Semiconductor
So I guess what I am saying is look at the datasheet, then come back with more questions. 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.
To participate you need to register. The pinout is in the datasheet. You must log in or register to reply here. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Did I mention you need to look at the datasheet. Welcome to our site!
Ordinary opamps cannot drive low impedance headphones. Electro Tech is datashset online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.
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. Articles Top Articles Search resources.

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.
LFN NTE Equivalent NTEM IC JFET INPUT OP AMP – Wholesale Electronics
The TL opamp has the same pin numbers. Thread starter grendal Start date May 6, In much the same way that logic circuits are designed, modern CAD packages automatically hook the power supply pins to the appropriate voltages. Potentiometer Questions Started by norbss Yesterday at I have the pin out but I guess what I’m trying to ask is what pins in the schematic are in use?
I think the circuit is supposed to give a hum when a nearby cell phone is ringing? Ld351n New posts Search forums. Not sure if it works not yet built it, so I’d want something with a low overload It is a level of detail that is not needed once you look at the datasheet. I don’t know if other similar opamps like the TL will overload the same.
