MSP430F6726A: Regarding SD24CAL

Part Number: MSP430F6726A

Hi,

I don't understand the operation when SDCAL = 1 in SD24_B. If you have any material that explains what this calibration function is and how to use it, please let me know where it is.

Hi,

With SD24CAL = 1, the offset of the modulator and PGA can be measured in a single conversion and calibrated in software afterwards. Setting SD24CAL shorts the inputs so the value measured can be used as an offset error for the actual measured signals.

We don't have any guide on the calibration because it is a very easy operation.
