Table 4-1.
Absolute Maximum Ratings*
Operating Temperature (Industrial)...............-40
° C to +85° C
*NOTICE:
Stresses beyond those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.
This is a stress rating only and functional operation of
the device at these or other conditions beyond those
indicated in the operational sections of this specification
is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reli-
ability.
Storage Temperature ................................... -55°C to +150°C
Power Supply Input
on VBAT.......................................................... -0.3V to +5.5V
on VDIG, AVDD .............................................. -0.3V to +3.6V
