(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. Operation of the device beyond the maximum Operating
Ratings is not recommended.
(2) All voltages are measured with respect to GND = 0V, unless otherwise specified.
(3) When the input voltage at any pin exceeds the power supplies (that is, V_IN < GND or V_IN > V_A), the current at that pin should be limited
to 10 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 10 mA to five.
(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 listed above will be reached only when the ADC141S626 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 a 100 pF capacitor discharged through a 1.5 kΩ resistor. Machine model is a 220 pF capacitor discharged
through 0 Ω. Charge device model simulates a pin slowly acquiring charge (such as from a device sliding down the feeder in an
automated assembler) then rapidly being discharged.
