Electrical Characteristics (continued)

Note 1: 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 guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics.

Note 2: Human body model, 1.5 k

Ω 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 unless otherwise specified.

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 =10MΩ 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: RL connected to V

+/2. For Sourcing Test, V

O > V

+/2. For Sinking tests, V

O < V

+/2.

Note 12: Output shorted to ground for sourcing, and shorted to V+ for sinking short circuit current test.

Note 13: VID is differential input voltage referenced to inverting input.

Note 14: Limits guaranteed by design.

Note 15: See the Typical Performance Characteristics and Application Notes sections for more details.
