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_IN< GND or V_IN> V_A), 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_Apin. The current into the V_Apin is limited by the Analog Supply Voltage specification.

Note 4: The absolute maximum junction temperature (T_Jmax) for this device is 150°C. The maximum allowable power dissipation is dictated by T_Jmax, the

junction-to-ambient thermal resistance (θ_JA), and the ambient temperature (T_A), and can be calculated using the formula P_DMAX = (T_Jmax − T_A)/θ_JA. 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 kΩ 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: Min/max specification limits are guaranteed by design, test, or statistical analysis.

Note 10: Clock may be either high or low when CS is asserted as long as setup and hold times t_CSUand t_CLHare strictly observed.
