Point of ADC saturation really depends on your reference voltage and your chosen prescaling. If you use the 1.2V VBG internal reference voltage the ADC range will be 0-1.2V with a saturation of 1.2V. This…

According to the nRF51882 Product Specification, the input voltage on any IO Pin must not exceed VDD + 0.3V. This means that ADC inputs must not exceed 2.1V if the nRF51822 is supplied by 1.8V, is this…

There are basically two rules to follow when deciding max voltage on AIN pins: The ADC should not be exposed to higher voltage than 2.4V on an input pin AIN after prescaling GPIO pin should not…
