The ADE7760 is a high accuracy, fault tolerant, electrical energy
measurement IC intended for use with 2-wire distribution
systems. The part specifications surpass the accuracy require-
ments as quoted in the IEC61036 standard.
The only analog circuitry used on the ADE7760 is in the ADCs
and reference circuit. All other signal processing (such as multi-
plication and filtering) is carried out in the digital domain. This
approach provides superior stability and accuracy over extreme
in environmental conditions and over time.
The ADE7760 incorporates a fault detection scheme similar to
the ADE7751 by continuously monitoring both the phase and
neutral currents. A fault is indicated when these currents differ
by more than 6.25%.
The ADE7760 supplies average active power information on the
low frequency outputs F1 and F2. The CF logic output gives
instantaneous active power information.
The ADE7760 includes a power supply monitoring circuit on
the VDD supply pin. Internal phase-matching circuitry ensures
that the voltage and current channels are matched. An internal
no-load threshold ensures that the ADE7760 does not exhibit
any creep when there is no load.
