(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see
the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics
may degrade when the device is not operated under the listed test conditions.
(2) If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications.
(3) For soldering specifications: see product folder at www.ti.com and http://www.ti.com/lit/SNOA549.
(4) When the input voltage at any pin exceeds the power supplies (that is, V
IN
< AGND or V
IN
> V
A
or V
D
), the current at that pin should 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.
(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
. In the 16-pin TSSOP, θ
JA
is 96°C/W, so P
D
MAX = 1,200 mW at 25°C and 625 mW at the maximum
operating ambient temperature of 105°C. Note that the power consumption of this device under normal operation is a maximum of 12
mW. The values for maximum power dissipation listed above will be reached only when the ADC128S052 is operated in a severe fault
condition (e.g. when input or output pins are driven beyond the power supply voltages, or the power supply polarity is reversed).
Obviously, such conditions should always be avoided.
(6) Human body model is 100 pF capacitor discharged through a 1.5 kΩ resistor. Machine model is 220 pF discharged through ZERO ohms
