11. BASIC APPLICATION CIRCUITS
Figure 14 shows the CS5464 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 CS5464 must be referenced to the line side of the
power line. This means that the common-mode poten-
tial of the CS5464 will track the high-voltage levels, as
well as low-voltage levels, with respect to earth ground.
Isolation circuitry is required when an earth-ground-ref-
erenced communication interface is connected. A cur-
rent transformer (CT) is connected to the return line
current, which implements the tamper detection circuit.
