Data Sheet
ELECTRICAL CHARACTERISTICS—MIXED 5 V/3 V OR 3 V/5 V, 105°C OPERATION1
5 V/3 V operation: 4.5 V ≤ VDD1 ≤ 5.5 V, 2.7 V ≤ VDD2 ≤ 3.6 V; 3 V/5 V operation: 2.7 V ≤ VDD1 ≤ 3.6 V, 4.5 V ≤ VDD2 ≤ 5.5 V; all
minimum/maximum specifications apply over the entire recommended operation range, unless otherwise noted; all typical specifications
are at TA = 25°C; VDD1 = 3.0 V, VDD2 = 5 V or VDD1 = 5 V, VDD2 = 3.0 V. These specifications do not apply to ADuM1400W, ADuM1401W,
and ADuM1402W automotive grade versions.
