ELECTRICAL CHARACTERISTICS (continued)
(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)
