SPRUJ53B April 2024 – September 2024 TMS320F28P550SJ , TMS320F28P559SJ-Q1
This error occurs due to mismatches in the Op-Amp gain. After the offset error has been removed, the remaining error, the gain error appears as a scaled error that increases in magnitude with increasing PGA output voltage, see Figure 18-8. The hardware trim targets the gain performance so that the hardware trim falls within the data sheet specifications.
