1. Below disruptive current conditions, a stressed channel will store the maximum conversion value for analog inputs
greater than VRH and the minimum conversion value for inputs less than VRL. This assumes that VRH ≤ VDDA and
VRL ≥ VSSA due to the presence of the sample amplifier. Other channels are not affected by non-disruptive con-
ditions
2. Input signals with large slew rates or high frequency noise components cannot be converted accurately. These
signals also interfere with conversion of other channels.
3. Exceeding limit may cause conversion error on stressed channels and on unstressed channels. Transitions within
the limit do not affect device reliability or cause permanent damage.
4. Input must be current limited to the value specified. To determine the value of the required current-limiting resistor,
calculate resistance values using positive and negative clamp values, then use the larger of the calculated values.
5. This parameter is periodically sampled rather than 100% tested.
6. Applies to single pin only.
7. The values of external system components can change the maximum input current value, and affect operation.
A voltage drop may occur across the external source impedances of the adjacent pins, impacting conversions on
these adjacent pins. The actual maximum may need to be determined by testing the complete design.
8. Current coupling is the ratio of the current induced from overvoltage (positive or negative, through an external
series coupling resistor), divided by the current induced on adjacent pins. A voltage drop may occur across the
external source impedances of the adjacent pins, impacting conversions on these adjacent pins.
