This parameter is not tested for Q and M suffix devices.
(2)
Due to the x2 output buffer, a reference input voltage
≥ (V
DD-0.4 V)/2 causes clipping of the transfer function. The output buffer of the
internal reference must be disabled, if an external reference is used.

Power supply rejection ratio at zero scale is measured by varying VDD and is given by: PSRR = 20 log [(EZS(VDDmax) -
EZS(VDDmin))/VDDmax]
