(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Recommended Operating Ratings indicate conditions for which the device is functional, but do not ensure specific performance limits. For ensured specifications and test conditions, see the Electrical Characteristics. The ensured specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions.

(2) All voltages are measured with respect to GND = 0 V, unless otherwise specified

(3) When the input voltage at any pin exceeds the power supplies (that is, less than GND, or greater than V_A), the current at that pin must 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.

(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 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 must always be avoided.

(5) See the section entitled "Surface Mount" found in any post 1986 National Semiconductor Linear Data Book for methods of soldering surface mount devices.

(6) The analog inputs are protected as shown below. Input voltage magnitudes up to V_A + 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_A or below GND by more than 100 mV. For example, if V_A is 2.7V_DC, ensure that −100mV ≤ input voltages ≤2.8V_DC to ensure accurate conversions.

(7) Typical figures are at T_J = 25°C, and represent most likely parametric norms. Test limits are specified to TI's AOQL (Average Outgoing Quality Level).

(8) This parameter is specified by design and/or characterization and is not tested in production.
