LMTF Datasheet(PDF) – National Semiconductor (TI)

The thermal resistance of the T version including mica insulator and paste is about 1. The 1nf capacitor at each input terminal are connected from the positive side to ground or or from the ground to chassis?

Simon Jones on August datasheeet, at 4: This helped me have the courage to continue with my own Gainclone amp project. Although its a bit more work, I prefer the T lm3886t for the 0. Cant wait to see post on power supply!

I would like to ask some questions. George on October 4, at 3: Robert Reed on October 31, at 1: The capacitor is there to filter any radio frequencies picked up by the chassis.

Your email address will not be published. In the rest everything is equal to the circuit.

Probably 1 volt too? The means to do so have been provided.

YNM on August 23, at Mohammad fahmawi on September 17, at 4: High frequency oscillation current will be impeded by the inductor and be forced to flow through the resistor, which will dampen it.

Use two smaller transformers and put bridge and caps on amplifier board. You can really feel it. I wish I had had this guide years ago when I first tried building an LM datazheet.

Do you think you could post the exhaustive list, brandd and referenced of the components? I datasheeh the sound my LM amp produces is much sweeter and softer than my Yamaha. I was wondering the same thing. As C13 is used to stabilize the amplifier I would just like confirmation that the parts list and silkscreen datashfet correct. I ordered exactly the chassis and heatsink as specified and there is no way that the heatsink will fit in that chassis.

The is in fact the smaller- the 47pF is the bigger one! If a separate supply is provided for each channel with separate capacitors bank for each channel, or even possibly with two power transformershow should grounding be organized?

It is hard to resist from building this amp: I have a transformer that feeds 22V at 7A. Thanks for the explanation. Your LM article is fantastic. Jeffery Lockmiller on November 7, at 5: Thomas on May 29, at I had the same, and i placed the order anyway. Robert Reed on August 15, at 3: Anyone has any idea on how to be qualified in order to build this amplifier without major mistakes?

The power ground and signal ground are the only ground networks on the PCB. Due to the length of this post, I decided not to cover the power supply in detail, but I may do so in the future. Use low ESR bulk storage caps and minimize inductance lengths.

Im beginning to not trust this beast. Is there any reason why the input capacitor C1 has such a huge voltage rating well above the theoretical maximum of The board layout has allowed for flexibility which will allow for experimenting with components.

Dr Dorkmeister on May 21, at Thanks a million for the detailed top quality guidance. The LM has one negative power supply pin pin 4 and two positive power supply pins pins 1 and 5. Second is to place fuse at the output end of the lytics. Chip amps sound mediocre Reply.
