Can you point me to an application note or some other documentation that provides recommendations on performing a Factory Calibration routine for the CYW20719B2 ADC?  We are using the ADC in Static mode (to monitor Battery voltage), but the observed unit-to-unit variation seems to indicate that we need to add a calibration routine.  

Apart from recommendations on how to best perform the calibration (number and type of measurements),  we're also looking for recommendations for how to store the Cal values (I suppose in NVRAM) and retrieve them during normal operation.

Hi @ChCh_3584941 

We don't have any specific Appnote on this other than the details available here: https://community.infineon.com/t5/Resource-Library/CYW20719-and-CYW20735-Analog-to-Digital-Converter...

Internally the driver is doing moving average filter. 

Can you please share your project and the details on variations which you are observing ? So that we can suggest accordingly.

Regards,

Anjana
