(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating
conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

DD
- 0.4 V)/2 causes clipping of the transfer function. The output buffer of the
internal reference must be disabled, if an external reference is used.
