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 per the Absolute Maximum Ratings. The
maximum package input current rating limits the number of pins that can safely exceed the power supplies.
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
J
J
) / 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

JA
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).
Note 5: Human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor. Machine model is a 220 pF capacitor discharged through 0 Ω. Charged
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
A
example, if V
is 3V, the digital input pins can be driven with a 5V logic device.

Note 8: To guarantee accuracy, it is required that V
be well bypassed and free of noise.
A
Note 9: Typical figures are at T
= 25°C, and represent most likely parametric norms. Test limits are guaranteed to National's AOQL (Average Outgoing Quality
J
Level).
Note 10: This parameter is guaranteed by design and/or characterization and is not tested in production.
Note 11: Spike suppression filtering on SCL and SDA will suppress spikes that are less than the indicated width.
Note 12: C
refers to the capacitance of one bus line. C
is expressed in pF units.

Note 13: The ADC will meet Minimum/Maximum specifications for f
up to 3.4MHz and V
= 2.7V to 3.6V when operating in the Quiet Interface Mode (See
SCL
A
Section
1.11 QUIET INTERFACE
MODE).
Note 14: The ADC121C021 will provide a minimum data hold time of 300ns to comply with the I
2
C Specification.
