LMTF Datasheet(PDF) – National Semiconductor (TI)

As an electrical engineering student, I love getting the chance to truly understand the process of creating the design. Circuit Basics on April 1, at 2: Hope the above was helpful.

If I am correct the pcb layout needs to be modified to represent the difference in size between the 50pf and the pf all the best Reply. I will add a comment to this post: I had the same, and i placed the order anyway. However If amp is run at near full load not likely heating effects of the transformer and bulk storage caps should be cooled as well.


The actual diode has only 2 posts rather than 3 as is shown in the data sheet. This helped me have the courage to continue with my own Gainclone amp project. Or is it just because the part is only manufactured like that by Mundorf?

The board layout has allowed for flexibility which will allow for experimenting with components. Robert on July 21, l3m886tf 9: Under normal operating conditions, low voltage ground loop currents flow through the resistor R1 to earth the chassis.

Thank you in advance! However, due to lack of deep knowledge in electronics, the project was lagging behind. Those are also metalized polypropylene film capacitors, but with a smaller footprint and dataeheet voltage ratings.

Thanks for all the hard work.

Use the metal datasheey version of the part. A person with or without electronics knowledge can follow this quite easily. Bob Pendergast on April 3, at Since the inductor will be carrying the full output current of the amplifier, the wire should be heavy gauge. Where would i put in a stereo potentiometer for volume control Reply.

Circuit Basics on June 19, at 6: Khurrum on September 21, at 9: I found the post about LM amplifier. A pre-amp with tone controls would be also be a welcome. Larger values will improve the bass response.

The PCB has 2 holes for the diodes, but the dataseet list specifies a 3 pin diode. Thanks a lot for sharing this wonderful job.

In this arrangement, the heat sinks provide some shielding from the Thiele networks and the AC wires leading to the transformer:. Did you mean X7R ceramic capacitors.
