Description
This logic output goes active high when a fault condition occurs. A fault is defined as a condition under
which the signals on V
condition is no longer detected. See the Fault Detection section.
This logic output goes logic high when negative power is detected, that is, when the phase angle
between the voltage and current signals is greater than 90°. This output is not latched and is reset when
positive power is once again detected. The output goes high or low at the same time as a pulse is issued
on CF.
This pin provides the ground reference for the digital circuitry in the ADE7760, that is, multiplier, filters,
and digital-to-frequency converter. This pin should be tied to the digital ground plane of the PCB. The
digital ground plane is the ground reference for all digital circuitry such as counters (mechanical and
digital), MCUs, and indicator LEDs. For good noise suppression, the analog ground plane should be
connected only to the digital ground plane at the DGND pin.
Calibration Frequency Logic Output. The CF logic output, active high, gives instantaneous active power
information. This output is intended to be used for operational and calibration purposes. See the Digital-
to-Frequency Conversion section.
Low Frequency Logic Outputs. F1 and F2 supply average active power information. The logic outputs
can be used to directly drive electromechanical counters and 2-phase stepper motors.
