1. Functional and tested operating conditions are given in Table 3-2 Recommended Operating Conditions on page 17. Absolute
maximum ratings are stress ratings only, and functional operation at the maximums is not guaranteed. Stresses beyond those
listed can affect device reliability or cause permanent damage to the device.
2. Caution: Transient VIN overshoots of up to OVDD + 0.8V, with a maximum of 4.0 V for 3.3 V operation, and undershoots down to
GND − 0.8 V, are allowed for up to 5 ns.
3. Caution: OVDD must not exceed VDD or AVDD by more than 2.1 V continuously. OVDD can exceed VDD or AVDD by up to 2.3 V
for up to 20 ms during power-on or power-off. OVDD must not exceed VD or AVDD by more than 2.3 V for any amount of time.
4. Caution: VDD/AVDD must not exceed OVDD by more than 1.0 V continuously. VDD or AVDD can exceed OVDD by up to 1.6 V for
up to 20 ms during power on or power off. VDD/AVDD must not exceed OVDD by more than 1.6 V for any amount of time.
5. Caution: AVDD must not exceed VDD by more than 0.5 V at any time.
