Hello Team,
I'm posting on behalf of my customer. Please see my customer inquiry below
I hope you are doing well. We use TIPD158 reference design to create own ADC module. The design is exact same copy of TIPD158. But we are encountering issue of heat. The Precision Programmable Reference (TL431BQDBZ) start heating up as we power the ADC module. Also there is no change at the output. It continuously stuck on 1mA.
Could you please help us finding issue with design or something else were we are making mistake?
Regards,
Renan
