I was given this circuit and there is a lf ic chip that is shown as a triangle, I’m not datasueet how to use the chip or what’s connected to where, I was never taught how to read this type of schematic. You must log in or register to reply here.

It is a level of detail that is not needed once you look at the datasheet. The data sheet has all the information that you require.

The TL opamp has the same pin numbers. The pinout is in the datasheet. 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.


Not sure if it works not yet built it, so I’d want something with a low overload I don’t know if other similar opamps like the TL will overload the same. Similar opamps are available.

Anyone know what pins I should use? Welcome to our site! The LF opamp is old and is not made anymore. So I guess what I am saying is look at the datasheet, then come back with more questions. Electro Tech is an datashfet community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

Ordinary opamps cannot drive low impedance headphones. Then it uses the strong UHF or microwave signal transmitted to overload the input of the opamp. Thread starter grendal Start date May 6, By continuing to use this site, you are consenting to our use of dataxheet.

Did I mention you need to look at the datasheet. For a better experience, please enable JavaScript in your browser before proceeding. Papabravo Well-Known Member May 6, 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.
