Description

REVP
This logic output will go logic high when negative power is detected, i.e., when the phase angle
between the voltage and current signals is greater that 90
°
. This output is not latched and will be
reset when positive power is once again detected. The output will go high or low at the same time as
a pulse is issued on CF.
This provides the ground reference for the digital circuitry in the AD7751, i.e., multiplier, filters
and digital-to-frequency converter. This pin should be tied to the analog ground plane of the PCB.
The digital ground plane is the ground reference for all digital circuitry, e.g., counters (mechanical
and digital), MCUs and indicator LEDs. For good noise suppression the analog ground plane
should only be connected to the digital ground plane at one point, e.g., a star ground.
Calibration Frequency Logic Output. The CF logic output gives
instantaneous real power
informa-
tion. This output is intended to be used for calibration purposes. Also see SCF pin description.
Low Frequency Logic Outputs. F1 and F2 supply
average real power
information. The logic outputs
can be used to directly drive electromechanical counters and two-phase stepper motors. See Transfer
Function section.
