Note 1: V+ and V- can have maximum magnitudes of 7V, but their absolute difference cannot exceed 13V.
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 in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
ELECTRICAL CHARACTERISTICS
(V_CC = +3.3V ± 5%, T_A = T_MIN to T_MAX. Typical values are at V_CC = +3.3V, T_A = +25°C, unless otherwise noted. See Note 2 for V+
and V- input voltage conditions.)
