† 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.

NOTE 1: Due to the x2 output buffer, a reference input voltage

≥ (VDD – 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.
