No extra resistors required- current is sourced from the opamp.
Your name or email address: I can see that the amplifier is actually amplifying, if I compare the strength of the input voltage versus the output voltage. However, unlike most internally compensated amplifiers, external frequency compensation may be added for optimum performance. I am sure with the new opamps, dqtasheet can design without using those transistors.
Complementary emitter followers inside the feedback loop will work.
Datasneet feature a factor-of-ten increase in. Now the opamp will perform as predicted and your gain equation will be valid. It doesn’t even have a power switch. Most audio opamps are 0.
Why is the amplification factor so low, even through the datasheet states the the amplification factor is calculated based on: Most come as dual. 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 speed over general-purpose devices without sacrificing dc performance. Me and this modern tech don’t get on so well.

Autistic 7, 2 15 You show three wires there.
The proposed follower would have a high current gain. The was a high performance chip in its dayBGW use them in their products extensively. You can use only the very old opamps that draw so much bias current. Do I need to drive the speaker with a transistor to make it louder or what would be the proper method? I’ve got a phono preamp with a bad LM P.
This particular unit was made in I think, but its possible the design is even older.

BinaryMikeJun 11, When I went to check for ripple again, I noticed the op-amp was hot after being on for maybe a minute. Been challenging the app engineer more than a few times in those semi conductor companies. An LM is not an audio power amplifier. This is at the input stage of the preamp, so low noise would be a priority.

Another problem is that the speakers output is as quiet satasheet an output from headphones. Moving the op-amp to the other channel moved the hum with it, dagasheet it still got hot. Sign up using Email and Password.
ConradHJun 11, Then you have a wide selections of better opamps. Since it’s still available, and cheap, I would go with the original. I’m trying to build a very simple circuit, that lm318l amplify an audio signal coming from a 3. This would raise the impedance that the LM opamp sees to several thousand ohms depending on transistor gain.
It is a very powerful IC, and easy to use and requires few components. 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?
