Where is the documentation for the location and proper use of the calibration data for PGA compensation?
I found an example for PGA compensation in controlSUITE, it defines a location in the calibration data OTP for PGA offset correction as:
#define PGA_COMP_LOC 0x3D7E61
I have found no other documentation about this compensation, the example is rather poorly documented regarding the gain compensation for the PGA (are different compensation values used for each PGA? Where ares these values located? What is their proper usage?). The only other reference to PGA compensation I found was a brief blurb in a heading in the datasheet (table 6-44 p.93) http://www.ti.com/lit/gpn/tms320f28052f.
Any help here would be appreciated.
Thanks,
Mark
