Note 1.

Exceeding the absolute maximum rating may damage the device.

Note 2.

The device is not guaranteed to function outside its operating rating.

Note 3.

I/O Pin Voltage is any external voltage to which an input or output is referenced.

Note 4.

The maximum allowable power dissipation is a function of the maximum junction temperature, T

J(max); the junction-to-ambient thermal

resistance,

JA; and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated using:

D = (TJ(max) – TA) ÷ θJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature.

Note 5.

Thermal resistance,

JA, applies to a part soldered on a printed-circuit board.

Note 6.

Devices are ESD protected; however, handling precautions are recommended. Human body model, 1.5k

Ω in series with 100pF.

Note 7.

All limits guaranteed by testing or statistical analysis.

Note 8.

Continuous short circuit may exceed absolute maximum T

J under some conditions.

Note 9.

CMRR is determined as follows: The maximum

∆V

OS over the VCM range is divided by the magnitude of the VCM range. The measurement

points are: V

CM = VV– – 0.3V, (VV+ – VV–)/2, and VV+ + 0.3V.

Note 10. R

L connected to 7.5V. Sourcing: 7.5V ≤ VOUT ≤ 12.5V. Sinking: 2.5V ≤ VOUT ≤ 7.5V.

Note 11. Device connected as a voltage follower with a 10V step input. The value is the positive or negative slew rate, whichever is slower.

Note 12. Referenced to input.
