Part Number: TLC2272-Q1

Dear team,

For the supply voltage, my customer's application voltage is +- 9V, 1V over than spec defined value, and this project has been released. My customer wants to know how risky this project is.

Thanks & Best Regards,

Hi Sherry,

Q; My customer wants to know how risky this project is.

The risk due to EOS damage is very high. Below is the warning paragraph when the absolute maximum ratings are exceeded. It is highly recommended that your customer will find a replacement for the components.

I did the equivalent op amp searches in our database for LTC2272-Q1, here are the search results:

If you have additional questions, please let us know.

Best,

Raymond

Thanks & Best Regards,

Hi Sherry,

sometimes the effective supply voltage can be decreased by such a scheme:

But to see whether this method can be used here, I would need to see the whole schematic.
