WARNING: Operation at conditions beyond the Recommended Operating Conditions may affect device reliability,

and functional operation beyond Recommended Operating Conditions is not implied.

Notes:

2. Any pin except supplies. Transient currents of up to ±100 mA on the analog input pins will not cause

SCR latch-up.

3. The maximum over/under voltage is limited by the input current.
