ELECTRICAL CHARACTERISTICS (continued)
(VAGND = 32V to 60V, VEE = 0V, VDD to VDGND = +3.3V, all voltages are referenced to VEE, unless otherwise noted. Typical values are at
VAGND = +48V, VDGND = +48V, VDD = (VDGND + 3.3V), TA = +25°C. Currents are positive when entering the pin and negative other-
wise.) (Note 2)
