Other Parts Discussed in Thread: DAC8775,
Dear TI,
I recently started using DAC8775 EVM to do few test on Analog output. During my testing, 2 EVM boards gone bad.
Found a small hole chipping on the DAC8775 IC on same location for both EVMs. Total 4 EVM are not working, other 2 EVM have different issues.
Please Find image of DAC8775 chipping.
Board 1:
Board 2: (Only 24V Supply to J2, Internal LDO was used with JP11, JP9 and JP13 Removed. No USB Dongle Connected and Jumper setting as per Datasheet)
Just out off box and this issue happened.

Can you please check which circuit is present on this area of IC Die, It will help to understand cause of IC Damage.
What caused this ?
Thank you,
Manikanta.
