TPS25750: How the ADCINx pins are decoded?

diverger

Part Number: TPS25750

From the datasheet, I learn that the decoded value from ADCINx pins determined the I2C address. But I can't figure out how the 0~7 value are calculated.

Thanks.

Hi,

Please refer to this table below:

This is how the ADCIN decode values 0-7 are calculated. We're working on including this in our next edit of the datasheet.

Apologies for the inconvenience and thank you for bringing it to our attention!

Thanks and Regards,

Where can I get this table? I guess it's a resistor divider tied to LDO_3V3. Right?

Hi,

Yes you are correct, the resistor divider is based on pullup to LDO_3V3.

Thanks and Regards,
