DC SAR10 ADC Specifications
The following table lists guaranteed maximum and minimum specifications for the voltage and temperature ranges: 4.75V to 5.25V
and -40°C ≤ T_A ≤ 85°C, or 3.0V to 3.6V and -40°C ≤ T_A ≤ 85°C, respectively. Typical parameters apply to 5V and 3.3V at 25°C and
are for design guidance only.

The internal voltage reference buffer is
disabled in this configuration.
When VREF is buffered inside the SAR10
ADC, the voltage level at P2[5] (when
configured as the external reference
voltage) must always be at least 300 mV
less than the chip supply voltage level on
the Vdd pin.
(V_VREFSAR10 < (Vdd - 300 mV) ).
