    Hi,

    Thank you for using E2E Forum and for showing interest in ISO1050DW.
    Like it is mentioned in the datasheet Pin 9 & Pin 10, both of which are GND2, are internally connected to each other and the impedance between them should be close to 0 Ω. Is this a fresh unused sample or is it a used one? Do you see this impedance with only one sample or do you see it on multiple samples?
