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 AGND = 32V to 60V, V EE = V DGND = 0V, T A = -40 N C to +105 N C. All voltages are referenced to V EE , unless otherwise noted. Typical
values are at V AGND = 54V, T A = +25 N C, and default register settings. Currents are positive when entering the pin, and negative
otherwise.) (Note 2)
