The DS for that chip is full of contradictions, doesn't engender confidence that the designers knew what they were doing.
Just a couple of examples - the absolute max supply is 38V but when shown as two separate supply voltages, the max is +/-12V. The abs max junction temp is shown as 70oC but the highest recommended ambient operating temp is 75oC.

It seems that Profusion is not hosting the latest datasheet.

A 4W @4ohm amplifier module that use CS6A4989 is now available in
http://www.eltim.eu/data/mediablocks/ELTIM PA-4989.pdf
It's linear, low distortion and power efficient.
