On all other products, production.

This would raise the impedance that the LM opamp sees to several thousand ohms depending on transistor gain. But the problem is, it’s amplification level appears to be only a factor of 6x. It seems that your IC can not provide enough current and it is not designed for audio applications.

Your limitation is actually you need a single opamp, not a dual!!!! The was a high performance chip in its dayBGW use them in their products extensively. Complementary emitter followers inside the feedback loop will work. If the datwsheet used with a discrete front end, as they do in the old app notes, you can’t just put another opamp in there.

LM318P, DIP-8

Email Required, but never shown. Home Questions Tags Users Unanswered. Most come as dual. I look for at least 20mA output current. Moving the op-amp to the other channel moved the hum with it, and it still got hot.

Sign up using Email and Password. The LM and LM are obsolete and are no longer supplied. No extra resistors required- current is sourced from the opamp. It is designed for audio applications. The actual current gain is roughly the HFE of your transistors.

You have to check the schematic to see if they’re using the offset pins as the inputs. OK, well if it has to use the original piece, I guess thats what I’ll do. They feature a factor-of-ten increase in. Even if I crank up the power supply of LM to 20v – the speakers volume doesn’t increase. This considerably simplifies their application because no external components are necessary for operation. New filter caps helped, but didn’t make it go away.

For phono preamp, I’d try the LME It is important the opamp be able to drive.

As far as I understood, I will get very limited current supply out from the op-amp and won’t be able to drive the speaker directly, correct? On all other products, production processing does not necessarily include testing of all parameters. Most audio opamps are 0. Do I need to drive the speaker with a transistor to make it louder or what would datashdet the proper method?

Things I usually look for audio opamps are: Michael George 1, 8 34 Products conform to specifications per the terms of Texas Instruments. Discussion in ‘ DIY ‘ started by gadget73Jun 11, Yes, that’s the circuit I described from the National Semi app notes. Been challenging the app engineer more than a few times in those semi conductor companies.

ConradHJun 12, The LM is not designed to drive the speaker directly. Your name or email address: Been to Linear Tech to show how their ADC fails, two of the app circuit on switching regulator oscillate.

Do you already have an account? This unit has two of these, so I’d replace both.

Since I have to replace it, is there something that would be an upgrade at a reasonable price? Since it’s dataaheet available, and cheap, I would go with the original.

You show three wires there.
