Difference between CS8673 and TPA3116

[deanrantala]

Oh yeah... here is the post-translated (re-combined) PDF version of the CS8673 for those who want a single PDF download.

Quality is so-so, but should give pretty much anyone all the info they need to build a circuit around this chip. Especially if you ALSO have the original datasheet side-by-side.

any news on your project?

Did a listening test with a whuzi audio cs8673 chip amplifier with a solar panel directly powered

Thread 'Class D amp directly solar powered?'

2025-02-05 7:49 am

I have a 2x25 Watt class D amp with CS8673 chip.

It can take maximum voltage of 24 Volts.

I have a 60 watt solar panel with maximum open circuit voltage of 22 Volts.

Is it possible to power such an amplifier directly with a solar panel with maybe some filtering capacitor of several thousand uF? Or should filtering be omitted ?

I live in egypt here you have always sun and it never rains.

Anyone tried running a class D amp like this?

Add 4700uf / 35v cap ti the panel output and you should be fine.

I had lying around 35v 6x6.800 uF and used them

Works nice!

Has anyone experimented with changing the inductors and caps on the CS8673 boards?
If so, do you have any observations to share?
Thank you.
