Note: 
1. These values are based on simulation. They are not covered by production test limits or
characterization.
2. Limit the input common mode voltage using the following equations (where, VCM_IN is the input
channel common mode voltage):
When CTRLA.R2R = 0:
VCM_IN < 0.75*VREF
VCM_IN > Maximum of (0, VREF-VDDANA-0.7, 1.25*VREF-VDDANA)
3. When SAMPCTRL.OFFCOMP is disabled, Ts is a function of the SAMPLEN[5:0] register value.
