MAX10 - Stress limit characterization

[FrankK]

Hello,

what is the tolerated stress limit in [mA] and [time duration] for port pin Vref of (single supply) MAX10 device (10MxxSA) considering the following scenario?

(Vref  > Vcc_one) and  (Vref < 3.3V) for t < x ms

Assuming a power-up sequence, in which Vref might startup ahead of Vcc_one.

MAX10 datasheet, ADC user and connection guideline doesn’t provide and data about stress limits.

Thanks in advance.

Hi,

I also might not know if we have or not the information, but as far as I know, we do have only the absolute maximum ratings for the DC output current per pin, the DC input voltage and also the absolute maximum ratings for the supply voltage pin for single supply device.

Hi,

thanks for your reply. I'm aware about the specified max. ratings, given by the datasheet but still looking for values about above described stress limits.
Can you forward my query to your design centre experts?

Hi,

I tried to ask around regarding the stress limits, but I could not find any information.

However, the first scenario (Vref > VCC_ONE) is not allowed per table 34 of the datasheet. It shows the maximum voltage allowed on VREF is VCC_ONE, with a minimal voltage of VCC_ONE - 0.5V.  

When operating within these specifications, ADC_VREF will only consume 10uA of leakage current (table 11).

I afraid this is out of Intel specification provided.
