Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those listed in the operational sections
of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
PERFORMANCE ISSUES THAT MAY AFFECT
BILLING ACCURACY
The ADE7761A 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
2P
– V
2N
complies with the
conditions described in Figure 34, 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
2P
– V
2N
does not comply with
the conditions described in Figure 34, the ADE7761A 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 ADE7761A about the
following:
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 ADE7761A is in Case 2 must
be decided knowing that the entity measured by the
ADE7761A in this case is ampere-hour and not watt-hour.
Users should be aware of this limitation and decide if the
ADE7761A is appropriate for their application.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
