Hello Weimang,

Unfortunately we can't locate the ESD information for the XTR115/116.

It would take at least a month to generate ESD data for the product, is it necessary for us to perform these tests?

Hello Weiming,

We were able to find the original ESD data for the XTR115/116. It was successfully tested with 2kV human body model ESD and 300V machine model.

The TI Designs Precision http://www.ti.com/tool/tipd126 describes a system with the PGA309 + XTR117 that successfully passes a common suite of IEC61000-4 transient and EMI/RFI testing, make sure you have a similar protection scheme on your design to protect the XTR and PGA devices.

Do you have a schematic to share?
