1 All accuracy numbers assume the ADC is calibrated with VREFH = VDDAD

2 Typical values assume VDDAD = 3.0 V, Temp = 25°C, Fadck= 20 MHz unless otherwise stated. Typical values are for reference

only and are not tested in production.

3 Offset error is same as ZSE, error measured at 0 V with zero scale.

4 Gain error is FSE-ZSE (same as FSE-EO).
