Help Determining Possible Damage to an ADC in a MAX10

Hi MKirk,

Try by enabling/disabling the clamp diode, we can limit overshoot or undershoot.See if it works.

Also refer below link page 5

https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/an/an447.pdf

1. ADC is fine as per the report, The test for linearity confirms that. but according to datasheet page 5 Maximum Allowed undershoot to –2.0 V for input currents less than 100 mA and periods shorter than 20 ns.

However Intel is not recommending or guaranteeing the performance at Absolute Maximum Ratings.

Please do check old case with similar issuse
