58.8.4.4.1 Differential Mode

In Differential mode, the offset is defined when the differential input voltage is zero.

Figure 58-13. Gain and Offset Errors in Differential Mode

where:

  • Full-scale error EFS =(EFS+)-(EFS-), unit is LSB code
  • Offset error EO is the offset error measured for VIN=0V
  • Gain error EG=100 × EFS /4096, unit in %

The error values in the tables below include the sample-and-hold error as well as the PGA gain error.
