NOTE 1: V+ and V- can have maximum magnitudes of 7V, but their absolute difference cannot exceed 13V.

ABSOLUTE MAXIMUM RATINGS

These are stress ratings only and functional operation

of the device at these ratings or any other above those

indicated in the operation sections of the specifications

below is not implied. Exposure to absolute maximum

rating conditions for extended periods of time may

affect reliability and cause permanent damage to the

device.
