8 / 36 page  ADuM4470/ADuM4471/ADuM4472/ADuM4473/ADuM4474 Data Sheet Rev. 0 | Page 8 of 36 ELECTRICAL CHARACTERISTICS—5 V PRIMARY INPUT SUPPLY/3.3 V SECONDARY ISOLATED SUPPLY 4.5 V ≤ VDD1 = VDDA≤ 5.5 V; VDD2 = VREG = VISO = 3.3 V; fSW = 500 kHz; all voltages are relative to their respective grounds; see the application schematic in Figure 48. All minimum/maximum specifications apply over the entire recommended operating range, unless otherwise noted. All typical specifications are at TA = 25°C, VDD1 = VDDA = 5.0 V, VDD2 = VREG = VISO = 3.3 V. Table 3.
