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 this data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
Notes:
Analog and battery voltages are referenced to AGND; digital (logic) voltages 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.
Some of the known examples of conditions that cause such potentials during powering are (1) an inductor connected to Tip and Ring that can
force an overvoltage on V
BAT
through external components if the V
BAT
connection chatters, and (2) inductance in the V
BAT
lead that could reso-
nate with the V
BAT
filter capacitor to cause a destructive overvoltage.
