ADS1018: failed EN 6000-4-2 8kV ESD Discharge test

Kevin,



I assume that you are refering to the IEC 61000-4-2 standard testing for ESD. Note that this device is rated to 4kV for the HBM ANSI/ESDA/JEDEC standard as you can find in the datasheet.



The ESD standards are a bit different between the one you mentioned and the JEDEC standard listed in the datasheet, but they may be similar in testing. For each standard, there are differences in the current and power for each ESD event. There are different rise times for the event, and there are a different number of events repeated for the tests.

I would guess that changing the layout will not help with protection. To protect against a higher ESD voltage, it may help to have external protection for the device. TVS, Schottky diodes, or extra series resistance can be added to the analog inputs of the device.
