AD8672 is very easy to be damaged

I already destroy more then 10 pcs AD8672 in my experiment.

I just use it as a low noise unit gain buffer.

Supply voltage are +/-12V

IN+ is connected to the reference output from LM399.
IN- and output is shorted to provide the negative supply voltage of AD5541.

But I found that the IN+ will follow the negative supply voltage ( ie, -12V ) in my PCB.

Can any one give me the advice?
