The current measurement should be around 75 µA. The three main contributors to the power savings are: The automatic timer triggers of the ADC to start conversion, using the ADC in consecutive sampling mode to prevent CPU intervention, and most importantly, the window comparator logic that only provides interrupts when the ADC conversion results falls within a user specific threshold. The hope is that these labs were useful in learning the functions of the ADC12_B module.
