BQ20Z80-V102: Determining accuracy and resolution of Current and Voltage measurements. (16bit ADC)

Part Number: BQ20Z80-V102

Tool/software:

It seems like the BQ2 chip has two ADCs:

-One to measure voltage across the sense resistor and convert to current.

-Another one to measure Pack Voltage and Temperature

I know one component of determining resolution is the fact that these ADCs are 16bit resolution.

However, there is another factor of the non-linearity error.  (In SLUS681B see below)



Does this integral non-linearity error apply to both ADCs or just the one associated with measuring current?

Thank you.
