THS3491: Can operating temperature extend?

Part Number: THS3491

Hi Team, 

This is customer request, can you please advise:

"

I am having a deadlock regarding the use of the THS3491 opamp. temperature conditions are specified as +85, but the graphs given in the datasheet cover 125. Normally a temperature is given as Ta Operating (100 or 105) in absolute maximum ratings, but it is not given here. Could we find out if there is data in this way?

"

Thanks in advance

Best Regards

  • The important number is the junction temperature, from absmax, continuous operating 125C is max for reliability. The ambient range is only 85C max as it might be difficult to stay below 125C Tj at higher ambient given t he high internal power - if you can keep the Tj below 125C max continuous, your ambient can go higher of course.
