Unless otherwise noted, the following specifications apply for V
C1 - C4 = 0.1µF. Typical values apply at V
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.
