ADuM5401W/ADuM5402W/ADuM5403W Data Sheet ELECTRICAL CHARACTERISTICS—3.3 V PRIMARY INPUT SUPPLY/3.3 V SECONDARY ISOLATED SUPPLY
Typical specifications are at TA = 25°C, VDD1 = VISO = 3.3 V, VSEL = GNDISO. Minimum/maximum specifications apply over the entire recommended operation range, which is 3.0 V ≤ VDD1, VISO ≤ 3.6 V, and −40°C ≤ TA ≤ +105°C, unless otherwise noted. Switching specifications are tested with CL = 15 pF and CMOS signal levels, unless otherwise noted.
