We are using the DA14683 in a new hardware design. The ADC functions correctly on all IO ports; however, the VBAT rail reading and Temperature Sensor readings are extremely high.
When loading Peripherals Demo to QSPI as a test and console connecting in:
VBAT rail voltage 3.074 V gives a reading of 4282 mV.
Temperature sensor reading gives: 96-120 Deg C when actual chip temp is 24 Deg. C. This is impeding battery charging.
Where do I even start looking with this one? When setting the attenuator on the temperature input, (1.2 to 3.6V range) I get a temp reading of -220 deg C.
Thanks,

We have a tutorial with an example code in order to configure the ADC in our support portal. Did you follow this tutorial? Please hit into this link :GPADC Adapter Concept. Otherwise, could you please provide me the code snippet that you are using in order to configure the ADC?
Thanks, PM_Dialog
Yes, using the peripherals_demo example program from the SDK, issue seemed to be linked to a leaky voltage source to the UART input on the one board. Unpackaged a few others and the issue has been resolved. It had seemed that voltage was bleeding onto one of the GPIO and backfeeding the ADC module. Thank you for the response.

Glad that you figured your issue out and thanks for the indication. If you have any other questions or issues, please fell free to create a new forum thread.
Thanks, PM_Dialog
