Hi,

Good Day. QFN package pin 18 ADDR, when not connect high, does this pin need to be ground? Please advise. Thank you very much.

Best Regards,

Ray,

This pin will determine the device address, as it is the last bit in the I2C address. If it is not pulled high, it will need to be tied to GND. It should not be left floating.
