Design information only, this parameter is not production tested.
±1% is assured at room temperature.
Overall output accuracy is directly affected by the accuracy of the external feedback network, 1% feedback resistors are recommended.
The 1% output voltage regulation is only guaranteed for a common mode voltage range greater than or equal to 0.7V at room
temperature.
