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