CS5466
5.7 Basic Application Circuit
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
shunt resistor configuration, the common-mode level 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.
