The ADE7759 is an accurate active power and energy measure-
ment IC with a serial interface and a pulse output. The ADE7759
incorporates two second-order Σ-∆ ADCs, a digital integrator
(on CH1), reference circuitry, temperature sensor, and all the
signal processing required to perform active power and energy
measurement.
An on-chip digital integrator allows direct interface to di/dt
current sensors such as a Rogowski coil. The digital integrator
eliminates the need for an external analog integrator and pro-
vides excellent long-term stability and precise phase matching
between the current and the voltage channels. The integratorcan be switched off if the ADE7759 is used with conventional
current sensors.
The ADE7759 contains a sampled waveform register and an
active energy register capable of holding at least 11.53 seconds
of accumulated power at full ac load. Data is read from the
ADE7759 via the serial interface. The ADE7759 also provides a
pulse output (CF) with frequency that is proportional to the
active power.
