TDA7498 class D amp could be used as a substitute?

[Bryant11]

I wonder if TDA7498 class D amp could be used as a substitute for a dead STK power module running at 39 Volt. If I remember well a class D amp needs the grounds of the output channels to be separated. One shared output ground, like in a standard amp chassis, may kill the class D amp. Anybody?

Only BTL power amps needs outputs tied not to ground, which unfornutately is the case of TDA7498 chip.  Not every class D amps requires that.
