limits apply for T
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
guaranteed to be 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: Parameters specified in dBFS indicate the value that would be attained with a full-scale input signal.
Note 3: All voltages are measured with respect to GND = AGND = DRGND = 0V, unless otherwise specified.
Note 4: When the input voltage at any pin exceeds the power supplies (that is, V
±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.
Note 5: The maximum allowable power dissipation is dictated by T
can be calculated using the formula P
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.
Note 6: Human Body Model is 100 pF discharged through a 1.5 kΩ resistor. Machine Model is 220 pF discharged through 0 Ω
Note 7: Reflow temperature profiles are different for lead-free and non-lead-free packages.
Note 8: The inputs are protected as shown below. Input voltage magnitudes above V
