Opinion about TPA6120 THT PCB drawing

[Julian RO]

I know that it is not the best solution to use THT components in the case of TPA6120... 🤓
Any advice?

A schematic would be nice 🙂

• Generally just read the layout considerations of the datasheet and use that as a basis for optimisation.
• If you switch the placement of your 50R and 10R resistors you can shorten the input traces which seem to be the most sensitive.
• If you rotate your 100nF and 100uF capacitors 90 degrees you can shorten and straighten the supply traces.

I guess you've seen this similar circuit?

Are you sure you want the inputs and outputs so close together?

 

[Julian RO]

What would be wrong if they are close? I mean what's going on?

 

[Andersonix]

Just a preference really: Some like to keep L&R inputs together...

Take a look at the datasheet §12.2. They keep in and out separated. And there is noted that if you use tht components not to have ground beneath them and the input output pins. Also, where are you going to connect the in and out grounds? I don't see any pins for that.

The Gnd connection is between the in and out pins.
