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.
