ADE7761
DISCLAIMER
The ADE7761 provides pulse outputs—CF, F1, and F2—
intended to be used for the billing of active energy. Pulses are
generated at these outputs in two different situations.
Case 1: When the analog input V
conditions described in Figure 32, CF, F1, and F2 frequencies
are proportional to active power and can be used to bill active
energy.
Case 2: When the analog input V
the conditions described in Figure 32, the ADE7761 does not
measure active energy, but a quantity proportional to kAh. This
quantity is used to generate pulses on the same CF, F1, and F2.
This situation is indicated when the FAULT pin is high.

Analog Devices Inc. cautions users of the ADE7761:
•
•
Billing active energy in Case 1 is consistent with the
understanding of the quantity represented by pulses on
CF, F1, and F2 outputs (watt-hour).
Billing active energy while the ADE7761 is in Case 2 must
be decided knowing that the entity measured by the
ADE7761 in this case is ampere-hour and not watt-hour.
Users should be aware of this limitation and decide if the
ADE7761 is appropriate for their application.
