I have got few samples of AD5422BREZ with date code 0835. I am facing a problem with these parts, It gets heated very badly after applying AVDD(+12V) to it. AVSS is tied to GND. I want to make it work as a unipolar 4-20mA output dac. Please help.
I have worked on the same part (different date code) in other projects and is working fine.
