I'm using ADV7181C for analog to digital conversion of video. But the output comes for few seconds and starts blinking. After that it gives the output for one or two seconds and goes blank for another one or two seconds. Blinking continues till the circuit is switched off and the ADV7181C IC gets extremely hot. I suspect the IC goes to a thermal shutdown due to over heating.


Almost all the guidelines mentioned in datasheet and support document were followed but no special measures were taken to enhance heat dissipation. Is there an overheating issue with this IC? What measures should be taken to overcome this issue? Thank you.
