6.1 Absolute Maximum Ratings

See (1)(2).
MIN MAX UNIT
Supply voltage ( V+– V− ) –0.3 6 V
Differential input voltage V– V+
Voltage at input/output pins (V– ) – 0.3 (V+) + 0.3
Junction temperature(3) –40 150 °C
Storage temperature, Tstg –65 150 °C
(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Recommended Operating Conditions indicate conditions for which the device is intended to be functional, but specific performance is not specified. For specifications and the test conditions, see the Electrical Characteristics.
(2) If Military/Aerospace specified devices are required, contact the TI Sales Office/Distributors for availability and specifications.
(3) The maximum power dissipation is a function of TJ(max) , RθJA, and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(max)–TA)/RθJA. All numbers apply for packages soldered directly into a PC board.

6.2 ESD Ratings

(1) Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary over time and will also depend on the application and configuration.
(2) 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 45 mA over long term may adversely affect reliability.
(3) For specified temperature ranges, see the CMVR parameter in DC Electrical Characteristics 1.8 V for the input common-mode voltage specifications.
(4) Connected as voltage follower with input step from V− to V+. Number specified is the slower of the positive and negative slew rates.
(5) Input referred, RL = 100 kΩ connected to V+/2. Each amplifier excited in turn with 1 kHz to produce VO = 3 VPP (For Supply Voltages < 3 V, VO = V+).
