AMC0330S-Q1: REFIN voltage reference

Tool/software:

Hello,

I have a question on the voltage reference applied to VREFIN. The datasheet says minimum 2.7V. Do you see any issue if I apply a 2.5V reference? 

Thank you,

Alice

    Hi Alice, 

    The VREFIN range listed in the datasheet is actually a typo, and we are working on updating it to the correct range.  The VREFIN pin should be ideally between 1.25V and VDD-1.25V.  As long as your VDD is above 3.75V, using a 2.5V reference should be fine.

    Thanks.
