Tool/software:

Hi team,

My customer is requesting us to provide easy possible maximum gain error calculation tool to compare between INA823 and INA849, considering thermal drift.

Could you provide the calculation tool like spreadsheet if available?

Best regards,

Hi Itoh-san,

I am not aware of a calculator tool but let me inquire as we have recently inherited this product family.

This E2E explains the calculations for gain error with a different INA but can still apply: https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1347449/ina851-gain-error

Please also see this apps note that goes in depth on error calculations.

Regards,
Ashley
