Note 1: The C1 to C0 differential input path is tolerant to 80V as long as the SHDN pin is deasserted.
Note 2: The C1 input is tolerant to a maximum V_DCIN + 0.6V. If SHDN is asserted, 20V is the maximum rating.
Note 3: Human Body Model to Specification MIL-STD-883 Method 3015.7.
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
(T_A = T_MIN to T_MAX, unless otherwise noted. V_DCIN = V_GNDu = +6.0V to +72V, typical values are at T_A = +25°C, unless otherwise
specified from -40°C to +105°C.)
