precise phase matching between the current and voltage
channels. T he integrator can be switched on and off based on
the current sensor selected.
T he ADE7753 contains an Active Energy register. It is
capable of holding more than 200 seconds of accumulated
power at full load. Data is read from the ADE7753 via the
serial interface. T he ADE7753 also provides a pulse output
(C F) with output frequency is proportional to the active
power.
In addition to rms calculation and active and apparent power
information, the AD E7753 also accumulates the signed
reactive energy. T he ADE7753 also provides various system
calibration features, i.e., channel offset correction, phase
calibration and power calibration. T he part also incorporates
a detection circuit for short duration low or high voltage
variations.
T he ADE7753 has a positive only accumulation mode which
gives the option to accumulate energy only when positive
power is detected. An internal no-load threshold ensures that
the part does not exhibit any creep when there is no load.
A zero crossing output (ZX ) produces an output which is
synchronized to the zero crossing point of the line voltage.
T his information is used in the ADE7753 to measure the
line's period. T he signal is also used internally to the chip in
the line cycle Active and Apparent energy accumulation
mode. T his enables a faster and more precise energy accumu-
lation and is useful during calibration. T his signal is also
useful for synchronization of relay switching with a voltage
zero crossing.
T he interrupt request output is an open drain, active low logic
output. T he Interrupt Status Register indicates the nature of
the interrupt, and the Interrupt Enable Register controls
which event produces an output on the
IRQ
pin.
T he ADE7753 is available in 20-lead SSOP package.

T he ADE7753 is an accurate active and apparent energy
measurements IC with a serial interface and a pulse output.
T he ADE7753 incorporates two second order sigma delta
ADC s, a digital integrator (on C H1), reference circuitry,
temperature sensor, and all the signal processing required to
perform RMS calculation on the voltage and current, active,
reactive, and apparent energy measurement.
An on-chip digital integrator provides direct interface to di/
dt current sensors such as Rogowski coils. T he digital
integrator eliminates the need for external analog integrator,
and this solution provides excellent long-term stability and
