GENERAL DESCRIPTION
The ADE7763 1 features proprietary ADCs and fixed function DSP
for high accuracy over large variations in environmental conditions
and time. The ADE7763 incorporates two second-order, 16-bit
Σ -? ADCs, a digital integrator (on Ch1), reference circuitry, a
perform active and apparent energy measurements, line-voltage
period measurements, and rms calculation on the voltage and
current channels. 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 precise
phase matching between the current and the voltage channels.
The ADE7763 provides a serial interface to read data and a
pulse output frequency (CF) that is proportional to the active
power. Various system calibration features such as 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 ADE7763 is available in a 20-lead SSOP package.
