Power IC FDA802 control volume

[Monserrat_Romero]

Is there any option to control output volume in Power IC FDA802?

This is a class D amp and you control volume by the data (I2S) , you send to it.

btw

You have the chip - or just wanna know? (because its NRND )

Ok, just double checking what I saw in datasheet.

Yes, I have it. Would it be discontinued, or why is it NRND?

[AScha.3]

I dont know - but usually NRND -> soon be discontinued . (but soon can be some years.)

If you want know more , maybe ask at STM direct :
