LM1875: Use as an op amp

I have just recently purchased these IC to use as a cheap voltage following buffer and am requiring it to be used as a current amplifier as well. All I require the op amp to do is to source about an amp or three to drive a .1 ohm resistor for my current amplifier circuit would there be any issues to the reliability of this chip? All I am doing as the buffer is taking a 10V ac sine wave and buffering the voltage source because my source cannot handle much current. The op amp only needs to supply 30mA of ac to drive the low side of a transformer. Does this sound doable for the LM1875 with proper cooling? I accidentally already burnt one of them because I was not properly cooling it but I want to make sure that was my only issue.
