Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: Differential input voltages greater than 1V will cause excessive

current to flow through the input protection diodes unless limiting

resistance is used.

sacrifice the advantages of the power supply rejection ratio matching). The
