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 RL = 10 MΩ connected to 5V. Each amp excited in turn with 1 KHz to produce about 10 VPP output.
