1. Refers to allowed random sequencing of power supplies
2. Transitions within the limit do not affect device reliability or cause permanent damage. Exceeding limit may cause
permanent conversion error on stressed channels and on unstressed channels.
3. Input must be current limited to the value specified. To determine the value of the required current-limiting resistor,
calculate resistance values using V POSCLAMP = V DDA + 0.3 V and V NEGCLAMP = –0.3 V, then use the larger of the
calculated values.
4. Condition applies to one pin at a time.
