Absolute Maximum Ratings
(@ T
A
= 25
°
C)
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended
periods of time can adversely affect device reliability.
Notes:
Analog voltages (V
CCA
, V
BATH
, and V
BATL
) are referenced to AGND and digital (logic) voltages (V
DD
) are referenced to DGND.
The IC can be damaged unless all ground connections are applied before, and removed after, all other connections. Furthermore, when power-
ing the device, the user must guarantee that no external potential creates a voltage on any pin of the device that exceeds the device ratings. For
example, inductance in a supply lead could resonate with the supply filter capacitor to cause a destructive overvoltage.
