Data Sheet ADuM1233 APPLICATIONS INFORMATION COMMON-MODE TRANSIENT IMMUNITY
The transient magnitude of the sinusoidal component is given by In general, common-mode transients consist of linear and dVCM/dt = 2πf V0 sinusoidal components. The linear component of a common- The ability of the ADuM1233 to operate correctly in the presence mode transient is given by of sinusoidal transients is characterized by the data in Figure 10 VCM, linear = (ΔV/Δt) t and Figure 11. The data is based on design simulation and is the where ΔV/Δt is the slope of the transient shown in Figure 12 maximum sinusoidal transient magnitude (2πf V0) that the and Figure 13. ADuM1233 can tolerate without an operational error. Values for immunity against sinusoidal transients are not included in The transient of the linear component is given by Table 6 because measurements to obtain such values have not dVCM/dt = ΔV/Δt been possible. The ability of the ADuM1233 to operate correctly in the
