Post as a guest Name. The good channel’s amp works fine in both sides, so I’m pretty certain its the chip that gave up. Email Required, but never shown. One opamp comes to mind is OPA single opamp: For phono preamp, I’d try the LME They feature a factor-of-ten dwtasheet in.

I am sure with the new opamps, you can design without using those transistors.

Single High-Speed Operational Amplifier

Been challenging the app engineer more than a few times in those semi conductor companies. On all other products, production. I’m hoping that with the power supply rebuilt it will stay good.

Datashheet problem is that the speakers output is as quiet as catasheet output from headphones. It is designed for audio applications.

I suggest using LM it is a power amplifier not only a voltage amplifier and it can provide gain up to OK, well if it has to use the original piece, I guess thats what I’ll do. BinaryMikeJun 11, Things I usually look for audio opamps are: Why is the lm18p factor so low, even through the datasheet states the the amplification factor is calculated based on: It works very well- I built one years ago.


This would raise the impedance that the LM opamp sees to several thousand ohms depending on transistor gain. Also, is that really a stereo 3.

Since I have to replace it, is there something that would be an upgrade at a reasonable price? No extra resistors required- current is sourced from the opamp. Sign up using Email and Password. Your name or email address: The proposed follower would have a high current gain. You have to check the schematic to see if they’re using the offset pins as the inputs.

AlanJun 11, You can use only the very old opamps that draw so much bias current. If you biased the follower well into class AB you should have something that will sound better than a chip at the expense of increased power drain.

Most come as dual. You show three wires there. Sign up using Facebook. Sign datasehet or log in Sign up using Google. Yes, that’s the circuit I described from the National Semi app notes. Discussion in ‘ DIY ‘ started by gadget73Jun 11, This particular unit was made in I think, but its possible the design is even older.

Do you already have an account? There may be no need, as the composite design was quite good. No, create an account now.

Log in km318p Sign up. 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? I’m trying to build a very simple circuit, that will amplify an audio signal coming from a 3. Overcompensation can be used with the amplifier for greater stability when maximum bandwidth is not needed.

This considerably simplifies their application because no external components are necessary for operation.

The LM and LM are obsolete and are no longer supplied. When I went to check for ripple again, I noticed the op-amp was hot after being on for maybe a minute. It is important the opamp be able to drive.

I don’t necessary think just because it’s in their application notes, then it’s a good circuit. Then you have a wide selections of better opamps.

There are a lot of much lower distortion opamps that are designed for high end audio. Even if I crank up the power supply of LM to 20v – the speakers volume doesn’t increase. Michael George 1, 8 34 Been to Linear Tech to show how their ADC fails, two of the app circuit on switching regulator oscillate.
