What parameter are included in AD8452 precision in Datasheet?

Hi ,

In AD8452,  a article say

  • Industry leading precise measurement of current and voltage better than 0.02% over 10⁰C temperature change

Analog Devices’ Integrated Precision Solution Enables Safer and Up to 50% More Efficient Battery Manufacturing | Analog … 

This one probably include only amp feature. 

Datasheet  say below

Datasheet description is " A precision
instrumentation amplifier (in-amp) measures the battery charge/
discharge current to better than ±0.1% accuracy, while an equally
accurate difference amplifier measures the battery voltage."

What parameter are included in 0.1%?

Best regards
