In order to achieve low power consumption, there are two types of sleep mode in DA14585 device, the extended and the deep sleep mode. In extended sleep mode, only the System RAM corresponding of the image size stays switched on. In deep sleep mode, only the wake up controller or the POR circuit remains switched on depending on the option selected. This means, that all the peripheral block (including the ADC) are powered off, so you are not allowed to use the them in any of sleep modes.
As I mentioned in my previous, all the peripherals blocks including the ADC are powered off when the device enters any of sleep modes. So, the device should be in active mode while the ADP sampling. In general, the average current consumption in active mode is around 600uA. But there is no clear answer on that since it depends on multiple factors and the application of course. Did you try to measure the power consumption? Thanks, PM_Dialog

Hi,
So, what is the lowest power mode that can be used while using ADC every 1ms ?
Thanks,
Roie
