Question about ADC power consumption

Hello, I am trying to develop a low power application by using nrf51822 EK board.

In " Reference manual v2.0, 11.1.3 System ON mode ", it says there is a mechanisms can automatically switch on and off the appropriate power sources depending on how many peripherals are active.

One of my application needs to detect the coin battery voltage I use ADC with TIMER2 to detect it. The detection period is relatively long (60~120 sec perhaps) I want to know when I enabled the ADC's interrupt (Avoiding interfere realtime application), Will the ADC is always "power on" even in IDLE state?

To reduce power consumption If the answer is yes, I think I can change my code by enabling ADC interrupt after the TIMER comparing event happens...

Thanks!
