Sorry - no pics at the moment.
Should be ok if the .1 uF caps are within a quarter inch of the chip. Otherwize, it may be oscillating and causing it to get hot. It should only get warm under normal use.
Did you include the 4.02K resistors that are shown in the evaluation board manual. That will keep the DC offset down when there is no source connected. It will go to the rail and draw mad current without it.
