ADS131B26Q1EVM-PDK: reason for R66 and R57

Part Number: ADS131B26Q1EVM-PDK

Hi team,

I see the EVM has two 0.1 Ohm resistors (R66 and R57) on the IOVDD and AVDD pins respectively. I don't see any documentation in the datasheet calling for these resistors nor explanation in the EVM user's guide. What's the purpose of these resistors?

Thanks,

Jacob

    Hi Jacob,

    those resistors are only there for us to measure the supply currents of the device. You would not use them in an actual design.
    I already asked the applications team to update the schematic with according comments in the schematic.
