ADE7763
TERMINOLOGY
Measurement Error
The error associated with the energy measurement made by the
ADE7763 is defined by the following formula:
Percent Error =
?
? True Energy ?
Phase Error between Channels
The digital integrator and the high-pass filter (HPF) in Channel 1
have a nonideal phase response. To offset this phase response
and equalize the phase response between channels, two phase-
correction networks are placed in Channel 1: one for the digital
integrator and the other for the HPF. The phase correction
networks correct the phase response of the corresponding
component and ensure a phase match between Channel 1
(current) and Channel 2 (voltage) to within ±0.1° over a range
of 45 Hz to 65 Hz with the digital integrator off. With the digital
integrator on, the phase is corrected to within ±0.4° over a
range of 45 Hz to 65 Hz.
Power Supply Rejection
This quantifies the ADE7763 measurement error as a percentage
of the reading when the power supplies are varied. For the ac
PSR measurement, a reading at nominal supplies (5 V) is taken.
A second reading is obtained with the same input signal levels
Data Sheet
when an ac (175 mV rms/120 Hz) signal is introduced to the
supplies. Any error introduced by this ac signal is expressed
as a percentage of the reading—see the Measurement
Error definition.
For the dc PSR measurement, a reading at nominal supplies
(5 V) is taken. A second reading is obtained with the same input
signal levels when the supplies are varied ±5%. Any error
introduced is again expressed as a percentage of the reading.
ADC Offset Error
The dc offset associated with the analog inputs to the ADCs. It
means that with the analog inputs connected to AGND, the
ADCs still see a dc analog input signal. The magnitude of the
offset depends on the gain and input range selection—see the
Typical Performance Characteristics section. However, when
HPF1 is switched on, the offset is removed from Channel 1
(current) and the power calculation is not affected by this offset.
The offsets can be removed by performing an offset calibration—
see the Analog Inputs section.
Gain Error
The difference between the measured ADC output code (minus
the offset) and the ideal output code—see the Channel 1 ADC
and Channel 2 ADC sections. It is measured for each of the
input ranges on Channel 1 (0.5 V, 0.25 V, and 0.125 V). The
difference is expressed as a percentage of the ideal code.
