(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltages are measured with respect to GND = 0 V, unless otherwise specified.
(3) If Military/Aerospace specified devices are required, please contact the TI Office/Distributors for availability and specifications.
(4) When the input voltage at any pin exceeds the power supply (that is, V
IN
< GND or V
IN
> V
A
), the current at that pin must be limited to
10 mA. The 20 mA maximum package input current rating limits the number of pins that can safely exceed the power supplies with an
input current of 10 mA to two. These specifications do not apply to the V
A
pin. The current into the V
A
pin is limited by the analog supply
voltage specification.
(5) The absolute maximum junction temperature (T
J
max) for this device is 150°C. The maximum allowable power dissipation is dictated by
T
J
max, the junction-to-ambient thermal resistance (θ
JA
), and the ambient temperature (T
A
), and can be calculated using the formula
P
D
MAX = (T
J
max − T
A
) / θ
JA
. The values for maximum power dissipation listed above is reached only when the device is operated in a
severe fault condition (that is, when input or output pins are driven beyond the power supply voltages, or the power supply polarity is
reversed). Such conditions must always be avoided.
