Basic Application Circuit
shunt resistor configuration, the common-mode level of
Figure 4 shows the CS5466 configured to measure
power in a single-phase, 2-wire system while operating
in a single-supply configuration. In this diagram, a shunt
resistor is used to sense the line current and a voltage
divider is used to sense the line voltage. In this type of
the CS5466 must be referenced to the line side of the
power line. This means that the common-mode poten-
tial of the CS5466 will track the high voltage levels, as
well as low voltage levels, with respect to earth ground
potential.
