(1)

Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may

degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond

those specified is not implied.

(2)

If the input signal can exceed 3.6 V, then a resistor greater than or equal to 25

Ω should be added in series with each of the analog

input pins to support input voltages up to 3.8 V. For input voltages above 3.8 V, the device can only handle transients and the duty cycle

of the overshoot should be limited to less than 5% for inputs up to 3.9 V.

(3)

The overshoot duty cycle can be defined as the ratio of the total time of overshoot to the total intended device lifetime, expressed as a

percentage. The total time of overshoot is the integrated time of all overshoot occurrences over the lifetime of the device.
