8.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted) (1)(2)(5)
MIN MAX UNIT
Supply voltage, VA −0.3 6.5 V
Voltage on any input pin −0.3 6.5 V
Input current at any pin(3) ±10 mA
Package input current(3) ±20 mA
Power consumption at TA = 25°C See (4)
Operating junction temperature 150 °C
Storage temperature, Tstg −65 150 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltages are measured with respect to GND = 0 V, unless otherwise specified.
(3) When the input voltage at any pin exceeds 5.5 V or is less than GND, the current at that pin should 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 (TJmax) for this device is 150°C. The maximum allowable power dissipation is dictated by TJmax, the junction-to-ambient thermal resistance (θJA), and the ambient temperature (TA), and can be calculated using the formula PDMAX = (TJmax − TA) / θJA. 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 operating ratings, or the power supply polarity is reversed).
(5) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications.

(1) Typical figures are at TJ = 25°C, and represent most likely parametric norms. Test limits are specified to AOQL (Average Outgoing Quality Level).
(2) This parameter is ensured by design and/or characterization and is not tested in production.
(3) To ensure accuracy, it is required that VA and VREF be well bypassed.
(4) Spike suppression filtering on SCL and SDA will supress spikes that are less than 50ns for standard-fast mode and less than 10ns for hs-mode.
(5) Applies to the Multiplying DAC configuration. In this configuration, the reference is used as the analog input. The value loaded in the DAC Register will digitally attenuate the signal at Vout.
