Part Number: TPA3244

Team,

I have two questions about TPA3244:

1. TPA3244 should be able to output 60W on 4ohm load. I am a bit confused why the power power specified in below spec is 25W? What is the difference?

2. What does the peak power in datasheet mean? Below figure is contiunous power or peak power?

Nic,

The first graph is for single ended application. You should go to BTL mode to find the 60W output power.

Thanks Dylan. I missed it. And what about the peak power question?

Nic,

The reason we talk about continous power or peak power is thermal. This plot we are using a good enough heatsink, doesn't has thermal problem.
