8.2.2 The AMC1100 in Energy Metering

Resulting from its immunity to magnetic fields, the AMC1100 can be used for shunt-based current sensing in smart electricity meter (e-meter) designs, as shown in Figure 38. Three AMC1100 devices are used for isolated current sensing. For voltage sensing, resistive dividers are usually used to reduce the common-mode voltage to levels that allow non-isolated measurement.
