This is a functional specification. Amplifier bandwidth decreases when the input common-mode voltage is driven in the range (V+ − 1 V) to V+. Common-mode error
voltage is typically less than 5 mV with the common-mode voltage set at 1 V below the positive supply.

OH
is defined as the difference
between the highest possible output voltage (V
