Note 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.
Note 2:
All voltages are measured with respect to GND = 0V, unless otherwise specified.
Note 3:
When the input voltage at any pin exceeds the power supply (that is, V
<
GND or V
>
V
), 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. The Absolute
Maximum Rating specification does not apply to the V
A
pin. The current into the V
A
pin is limited by the Analog Supply Voltage specification.
Note 4:
The absolute maximum junction temperature (T
max) for this device is 150C. The maximum allowable power dissipation is dictated by T
max, the
junction-to-ambient thermal resistance (
θ
), and the ambient temperature (T
), and can be calculated using the formula P
MAX = (T
max T
)/
θ
. The values
for maximum power dissipation listed above will be reached only when the device 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.
Note 5:
Human body model is 100 pF capacitor discharged through a 1.5 k
resistor. Machine model is 220 pF discharged through zero ohms
Note 6:
Reflow temperature profiles are different for lead-free and non-lead-free packages.
Note 7:
Tested limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
Note 8:
This is the frequency range over which the electrical performance is guaranteed. The device is functional over a wider range which is specified under
Operating Ratings.
Note 9:
Data sheet min/max specification limits are guaranteed by design, test, or statistical analysis.
Note 10:
Minimum Quiet Time required by Bus relinquish and start of the next conversion.
Note 11:
Measured with the timing test circuit shown in Figure 1 and defined as the time taken by the output signal to cross 1.0V.
Note 12:
Measured with the timing test circuit shown in Figure 1 and defined as the time taken by the output signal to cross 1.0V or 2.0V.
Note 13:
t
DIS
is derived from the time taken by the output to change by 0.5V with the timing test circuit shown in Figure 1. The measured number is then adjusted
to remove the effects of charging or discharging the 25 pF capacitor. This means that t
DIS
is the true bus relinquish time, independent of the bus loading.
