ADuM1400/ADuM1401/ADuM1402
ELECTRICAL CHARACTERISTICS—5 V, 125°C OPERATION 1
4.5 V ≤ V DD1 ≤ 5.5 V, 4.5 V ≤ V DD2 ≤ 5.5 V; all minimum/maximum specifications apply over the entire recommended operation range,
unless otherwise noted; all typical specifications are at T A = 25°C, V DD1 = V DD2 = 5 V. These specifications apply to ADuM1400W ,
ADuM1401W , and ADuM1402W automotive grade versions.
