10V Electrical Characteristics (continued)
Unless otherwise specified, all limits ensured for T_J = 25°C, V⁺ = 10V, V^− = 0V, V_CM = V_O = V ⁺/2, and R_L = 1 MΩ to V⁺/2.
Boldface limits apply at the temperature extremes.

(4) R_L connected to V⁺/2. For Sourcing Test, V_O > V⁺/2. For Sinking tests, V_O < V⁺/2.
(5) V_ID is differential input voltage referenced to inverting input.
(6) Output shorted to ground for sourcing, and shorted to V+ for sinking short circuit current test.
(7) Slew rate is the slower of the rising and falling slew rates.
(8) See the Typical Performance Characteristics and Applications Information sections for more details.
(9) Input referred, V⁺ = 10V and R_L = 10 MΩ connected to 5V. Each amp excited in turn with 1 KHz to produce about 10 V_PP output.
