BQ25882: About the temperature variation for TDIE_ADC.

Kengo.Y

Part Number: BQ25882

Hi team.

I'd like to know about the temperature variation for TDIE_ADC.

My customer plan to use the BQ25882 to measure ambient temperature.
So, how much is the temperature variation of TDIE_ADC?

Sincerely.
Kengo.

Hello Kengo,

The resolution of the ADC is 1degC. This should be the accuracy of the TDIE_ADC.

Hi Jing,

Could you tell me an additional question?

Is there a temperature accuracy in the die itself?
Or does TDIE_ADC include die temperature accuracy?

Sincerely.
Kengo.

The ADC reports the die temperature. So if the customer is reading the ADC for the die temperature then the ADC accuracy is what you are looking for.
