All limits guaranteed by testing on statistical analysis. Note 1. Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating the device outside its recommended operating ratings. Note 2. I/O Pin Voltage is any external voltage to which an input or output is referenced. Note 3. The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(max); the junction-to-ambient thermal resistance, θJA; and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated using: PD = (TJ(max) – TA) ÷ θJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature. Note 4. Thermal resistance, θJA, applies to a part soldered on a printed-circuit board. Note 5. Human body model, 1.5k in series with 100pF. Note 6. Common-mode performance tends to follow the typical value. Minimum value limits reflect performance only near the supply rails. Note 7. Continuous short circuit may exceed absolute maximum TJ under some conditions. Note 8. Shorting OUT to V+ when V+ > 12V may damage the device. Note 10. Device connected as a voltage follower with a 12V step input. The value is the positive or negative slew rate, whichever is slower.
