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.
