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 = 0 V, unless otherwise specified
Note 3: When the input voltage at any pin exceeds the power supplies (that is, less than GND, or greater than V
), the current at that pin should be limited to 10
A
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.
Note 4: The absolute maximum junction temperature (T
max) for this device is 175°C. 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

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 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: The analog inputs are protected as shown below. Input voltage magnitudes up to V
+ 300 mV or to 300 mV below GND will not damage this device.

However, errors in the conversion result can occur if any input goes above V
or below GND by more than 100 mV. For example, if V
is 2.7 V

Note 11: These parameters are worse case drift. Deltas are performed at room temperature Post OP Life. All other parameters no Deltas are required.
Note 12: Pre and post irradiation limits are identical to those listed in the “DC Parameters” and “AC and Timing Characteristics” tables, except as listed in the
“Radiation Electrical Characteristics” table. When performing post irradiation electrical measurements for any RHA level, T
= +25°C. See section 3.0 for dose
