I orderd an evaluation kit for DA7212. It has the mother board 170-04-A and the DA7212 daughter board 169-02-A. I have been trying to test the speaker output (or LINE output) by changing VDD_SP to external or internal. It worked yesterday. Today, I tested again and I've just found out the chip became hot and no output. I power cycle and could not fix it. It looks like the chip is dead.
The question is whether I can order just the DA7212 daughter card. The whole evaluation kit costs more than $300. I don't think my boss will approve another kit. In digikey they don't sell just the daughter card. Please help. Thanks,
