VOD represents the overdrive voltage, or the amount of voltage by which the threshold point has been exceeded.

See the Input-Referred Dynamic Error section.

The voltage at OUT must not be allowed to exceed the VREG voltage, which is always 2.4 V less than the supply. For example, when the supply voltage is 5 V and the

output current is 1 mA, the load resistor must not be more than (5 V – 2.4 V)/{1 mA × (1 + 20%)}, or 2.17 kΩ, to ensure the signal does not exceed 2.6 V. As the supply

increases, the output signal also can be increased, by the same amount.
