Request the Schematic Review with AD7322


My customer use AD7322 in their system which is used in military area.

And they have a issue about AD7322 related heat.

They say that their board has some AD7322 devices, but only one device located in U21 is too hot.

(When they touch the top of AD7322 in U21, they can feel too hot.)

So they request your confirmation about their schematics.

Q1) Would you confirm their circuit related AD7322 in attached schematic?'

Q2) Would you advise why this device is getting too much heat and how to prevent this heat to them?

Please advise me.

If you have any questions, please let me know
