Potentiometer Questions Started by norbss Yesterday at The pinout is in the datasheet. The TL opamp has the same pin numbers.
LFN 데이터시트(PDF) – STMicroelectronics
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.
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?
To participate you need to register. Thread starter grendal Start date May 6, The data sheet has all the information that you require. Click here to register now.
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?
