9. BASIC APPLICATION CIRCUITS
Figure 18
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 CS5463 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.

tem with complete isolation from the power lines. This
isolation is achieved using three transformers: a general
purpose transformer to supply the on-board DC power;
a high-precision, low-impedance voltage transformer,
with very little roll-off/phase-delay, to measure voltage;
and a current transformer to sense the line current.
