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)

Do not short circuit output to V+, when V+ is greater than 12V or reliability will be adversely affected.

(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)

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.

Typical Values represent the most likely parametric norm.

(2)

All limits are specified by testing or statistical analysis.

(3)

Input Offset Voltage Average Drift is calculated by dividing the accelerated operating life drift average by the equivalent operational time.

The Input Offset Voltage Average Drift represents the input offset voltage change at worst-case input conditions.
