ADC HAL power management

[Aaron]

Our chip seems to be running at ~500uA and I'm trying to narrow it down.

I'm doing periodic battery level checks on a timer using the ADC HAL. So at init I call nrf_adc_configure() and then in the timeout handler call nrf_adc_convert_single(). Doc for nrf_adc_convert_single says it puts ADC in STOP state. Is that sufficient or do I need to disable it also?

@Aaron: What is your sample rate of ADC ? Do you do anything other than sampling ADC ? BLE ? Doing a STOP task after you finish ADC sampling should be enough to put the ADC to low power. You don't have to disable it.
