Can I read the VBAT voltage of DA 1468x by DA 1468x itself? Is it possible using the ADC of DA 1468x? Or are there any way to measure without using that ADC?
Yes, there is a battery channel of the ADC, you will have to select in the GP_ADC_CTRL_REG in the GP_ADC_SEL the VBAT channel. Please check the peripherals demo example and the adc demo example. Additional information can be found in the datasheet.
The ADC includes a specific channel connected to the VBAT in order to measure the battery so you dont need to connect any additional ADC channel on the battery. In order to measure the voltage besides that i am not aware of any other way to do so.

Hi support!
Thank you for your response.
I think that the contents you responded are methods using built-in ADC.
Is there NO way to know the value of VBAT "without" using the built-in ADC?
