11.1.3 Calibration Tab
A calibration feature is integrated into the ADS1282 to correct for offset and gain errors. The
ADS1282EVM-PDK software is designed to allow the user to use either the built-in system calibration
commands or manually calibrate the device by directly entering the values for the offset and gain registers
of the ADS1282.
