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 ADE7755 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.
See Terminology section for explanation of specifications.

See Figure 1.
The pulsewidths of F1, F2, and CF are not fixed for higher output frequencies. See Frequency Outputs section.
The CF pulse is always 18 s in the high-frequency mode. See Frequency Outputs section and Table IV.
