ADE7754
–5–
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 the
ADE7754 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.

*Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent 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.
PIN FUNCTION DESCRIPTIONS
Pin No. Mnemonic Description
1CFCalibration Frequency Logic Output. This pin provides active power information. This output
is intended to be used for operational and calibration purposes. The full-scale output frequency
can be scaled by writing to the CFNUM and CFDEN registers. See the Energy to Frequency
Conversion section.
2 DGND This pin provides the ground reference for the digital circuitry in the ADE7754 (i.e. multiplier, filters,
and a digital-to-frequency converter). Because the digital return currents in the ADE7754 are small,
this pin can be connected to the analog ground plane of the whole system. However high bus
capacitance on the DOUT pin may result in noisy digital current, which could affect performance.
