The output voltage is in the unit gain circuitry and over the full input common-mode range.
The response time specified is a 100 mV input step with 30 mV overdrive.
The input common-mode voltage or either input signal voltage should not be allowed to go
negative by more than 0.3V. The upper end of the common-mode voltage range is VDD.
