It seems that TPA322x and 325x series are quite overlapping in parameters and performance. What is a basic guide to select proper IC for a specific application? Thanks

I found the answer partially here: https://www.ti.com/lit/ml/slyb233/slyb233.pdf?ts=1682065495297&ref_url=https%253A%252F%252Fwww.google.com%252F

I understand that TPA3220 is more power optimized however there is a new TPA3223 which is more powerful than TPA3250.

Hi Ivan

The TPA322x family would be newer than TPA324x/TPA325x, we would recommend to use TPA322x as the first choice. From using and function perspective, they are quite similar.

Thank you. This is the answer I needed to see.

P.S. is the attached image correct? TPA3223 specification seems inaccurate.

Hi Ivan

You are correct, I changed it. I'm also checking within the team if there's any update to this road map. But as far as I know, there's no new planning devices for this family.
