(1) All voltages are measured with respect to GND = AGND = DGND = DRGND = 0V, unless otherwise specified.
(2) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is specified to be 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. Operation of the device beyond the
maximum Operating Ratings is not recommended.
(3) When the input voltage at any pin exceeds the power supplies (that is, V_IN < AGND, or V_IN > V_A), the current at that pin should be
limited to ±5 mA. The ±50 mA maximum package input current rating limits the number of pins that can safely exceed the power
supplies with an input current of ±5 mA to 10.
(4) The maximum allowable power dissipation is dictated by T_J,max, the junction-to-ambient thermal resistance, (θ_JA), and the ambient
temperature, (T_A), and can be calculated using the formula P_D,max = (T_J,max - 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). Such conditions should always be avoided.
(5) Human Body Model is 100 pF discharged through a 1.5 kΩ resistor. Machine Model is 220 pF discharged through 0 Ω
(6) Reflow temperature profiles are different for lead-free and non-lead-free packages.
