Integrated isolated voltage-sensing use cases

Figure 6 shows the standard topology of a power-conversion system. For AC voltage sensing, you can use the AMC0380D04-Q1 without external high-voltage resistors (the green rectangle) or the AMC0330D-Q1, AMC0330S-Q1 or AMC0330R-Q1 with external high-voltage resistors (the yellow rectangle).

For DC voltage sensing, you can use the AMC0381D10-Q1 and AMC0386M10-Q1 without external high-voltage resistors (the blue rectangles) or the AMC0311D-Q1, AMC0311S-Q1 or AMC0311R-Q1 with external high-voltage resistors (the red rectangles).
