BQ41Z90: BQ41Z90 - ADC 18-bit input range

Davide Sarti

Part Number: BQ41Z90

Hello,

in the BQ41Z90 datasheet I found that SRP, SRN input ranges are -0.25V to 0.5V. However, the ADC 18-bit input range is not specified.

Is the ADC voltage range -0.25V to 0.5V as well?

Thanks in advance!

Hello Davide,

This is not spec'd in the current datasheet.

Hello Jonny,

Is this information somewhere else or would it appear in the datasheet in the future? I think it's an important information to have in order to correctly set the current sensing resistor.

Thanks in advance,

Davide

Hello Davide,

I agree, I have brought this up with the team, and this should be added to the documentation in the future. There should be a section describing the ADC accuracy similar to what we have for our other gauges.

Regards,

Jonny.
