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

Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at The schematics I’m familiar with for ics are like this one. Articles Top Articles Search resources.


Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. 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. It is a level of detail that is not needed once you look at the datasheet.

In much the same way that logic circuits are designed, modern CAD packages automatically hook the power supply pins to the appropriate voltages. Anyone know what pins I should use?

I think the circuit is supposed to give a hum when a nearby cell phone is ringing? The TL opamp has the same pin numbers.

Ordinary opamps cannot drive low impedance headphones. Not sure if it works not yet built it, so I’d want something with a low overload So I guess what I am saying is look at the datasheet, then come back with more questions. Replacement Transformer Started by ncag Today at 7: 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.


Then it uses the strong UHF or microwave signal transmitted to overload the input of the opamp. Thread starter grendal Start date May 6, Potentiometer Questions Started by norbss Yesterday at Click here to register now.
