Customer of mine would like to know if they can leave the AGNDAD (pin 45) floated if the internal ADC is not used?
Would it caused any mulfuction to this device?
Hi, Eng Lih Khaw,
It is recommended to keep the AGNDAD pin connected to GND plane even if the ADC is not used. This is done to ensure proper grounding between the internal connections with ADC block.
