Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is in-
tended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical characteristics.
Note 2: Human body model, 1.5 kΩ in series with 100 pF.
Note 3: 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.
Note 4: 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.
Note 5: Typical Values represent the most likely parametric norm.
Note 6: All limits are guaranteed by testing or statistical analysis.
Note 7: Do not short circuit output to V+, when V+ is greater than 13V or reliability will be adversely affected.
Note 8: Slew rate is the slower of the rising and falling slew rates.
Note 9: Input referred, V+ = 10V and RL = 100 kΩ connected to 5V. Each amp excited in turn with 1 kHz to produce about 10 VPP output.
Note 10: Limiting input pin current is only necessary for input voltages that exceed absolute maximum input voltage ratings.
Note 11: VID is the differential voltage on the non-inverting input with respect to the inverting input.
Note 12: VI is the input voltage.
