GENERAL DESCRIPTION
The ADE7753 1 features proprietary ADCs and DSP for high
accuracy over large variations in environmental conditions and
time. The ADE7753 incorporates two second-order 16-bit ? -Δ
ADCs, a digital integrator (on CH1), reference circuitry,
temperature sensor, and all the signal processing required to
line-voltage period measurement, and rms calculation on the
voltage and current. The selectable on-chip digital integrator
provides direct interface to di/dt current sensors such as
Rogowski coils, eliminating the need for an external analog
integrator and resulting in excellent long-term stability and pre-
cise phase matching between the current and voltage channels.
The ADE7753 provides a serial interface to read data, and a
pulse output frequency (CF), which is proportional to the active
power. Various system calibration features, i.e., channel offset
correction, phase calibration, and power calibration, ensure
high accuracy. The part also detects short duration low or high
voltage variations.
The positive-only accumulation mode 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. The zero-crossing output (ZX)
produces a pulse that is synchronized to the zero-crossing point
of the line voltage. This signal is used internally in the line cycle
active and apparent energy accumulation modes, which enables
faster calibration.
The interrupt status register indicates the nature of the interrupt,
and the interrupt enable register controls which event produces
an output on the IRQ pin, an open-drain, active low logic output.
The ADE7753 is available in a 20-lead SSOP package.
