Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is intended to be functional, but specific performance is not ensured. For ensured specifications and the test

conditions, see the Electrical Characteristics.

(2)

If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications.

(3)

Human body model, 1.5 k

Ω in series with 100 pF.

(4)

Limiting input pin current is only necessary for input voltages that exceed absolute maximum input voltage ratings.

(5)

Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in

exceeding the maximum allowed junction temperature of 150°C. Output currents in excess of ±30 mA over long term may adversely

affect reliability.

(6)

Do not short circuit output to V+, when V+ is greater than 13V or reliability will be adversely affected.

(7)

The maximum power dissipation is a function of TJ(MAX), θJA, and TA. The maximum allowable power dissipation at any ambient

temperature is PD= (TJ(MAX) - TA)/ θJA. All numbers apply for packages soldered directly into a PC board.
