nRF52832 current consumption in System OFF / No RAM retention / Wake on LPCOMP mode

Hi all,

The nRF52832 spec. document specifies that the current consumed in System OFF / No RAM retention / Wake on LPCOMP mode is 1.9uA. However, if I measure the current using the Nordic PPK, it is only ~0.4uA. I assume my software / SoC works correctly because I can see that the chip goes in to the system off mode and wakes up by LPCOMP interrupts.

Could anyone confirm if 1.9uA shown in the spec is a correct value? Do you have any idea why the actual measured current is much lower than the spec.?

Thank you.

Best,
Jay
