FAQ: After performing AD7124-4/AD7124-8 calibrations, do I need to use the offset and gain coefficients in my data output code calculations?

FAQ: After performing AD7124-4/AD7124-8 calibrations, do I need to use the offset and gain coefficients in my data output code calculations?

When the ADC performs the offset and gain calibrations, the resulting offset and gain coefficients are updated in the corresponding offset and gain registers. The ADC automatically applies these corrections to the ADC conversions; therefore, the customer does not have to worry about these coefficients. From a customer perspective, the standard equation to convert codes to volts are used, please refer to How to convert the AD7124-4/AD7124-8 data output Code to equivalent analog input voltage?
