Dear Team,

This was reported months ago and we still have incorrect formulas in the datasheet (last updated in April 2022).

Please fix as my customer also had an issue with this error.

Best regards,

Hi Daniel,

Can you point out exactly where in the datasheet you're saying the error is present?

Hi Daniel,

Thanks for bringing this to my attention.

Looks like that's what the correction is supposed to be. Theres a revision for the datasheet already in process that I'm adding this to although I'm not sure when it will be released.

Regards,

Yara
