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. Operation of the device beyond the maximum Operating Ratings is not recommended.
Note 2: All voltages are measured with respect to GND = 0V, unless otherwise specified.
Note 3: When the input voltage at any pin exceeds 5.5V or is less than GND, the current at that pin should be limited to 10 mA. The 30 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 three.
Note 4: The absolute maximum junction temperature (T
max) for this device is 150°C. The maximum allowable power dissipation is dictated by T
max, the

) / θ
junction-to-ambient thermal resistance (θ
), and the ambient temperature (T
), and can be calculated using the formula P
MAX = (T
max − T
. The values

for maximum power dissipation 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 operating ratings, or the power supply polarity is reversed). 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 0 Ω. Charge device model
simulates a pin slowly acquiring charge (such as from a device sliding down the feeder in an automated assembler) then rapidly being discharged.
Note 6: Reflow temperature profiles are different for lead-free packages.
Note 7: The inputs are protected as shown below. Input voltage magnitudes up to 5.5V, regardless of V
, will not cause errors in the conversion result. For

example, if V
is 3V, the digital input pins can be driven with a 5V logic device.

Note 8: Test limits are guaranteed to National's AOQL (Average Outgoing Quality Level).
Note 9: This parameter is guaranteed by design and/or characterization and is not tested in production.
Note 10: This parameter does not represent a condition which the DAC can sustain continuously. See the continuous output current specification for the maximum
DAC output current per channel.
