Data Sheet
For calibration, a first measurement should be done on I PA by
setting the SEL_I_CH bits (Bits[5:4]) to 0b01 in the CALMODE
register (Address 0x3D). This measurement should be compared
to the measurement on I PB . Measuring I PB can be forced by setting
the SEL_I_CH bits (Bits[5:4]) to 0b10 in the CALMODE register
(Address 0x3D). The gain error between these two measurements
can be evaluated using the following equation:
ADE5166/ADE5169/ADE5566/ADE5569
10
0
–10
–20
Error (%) =
Measurement ( I PB ) ? Measurement ( I PA )
Measuremen t ( I PA )
–30
The two channels, I PA and I PB , can then be matched by writing
–40
–Error(%)/(1 + Error(%)) × 2 12 to the IBGAIN register
(Address 0x1C). This matching adjustment is valid for all energy

di/dt CURRENT SENSOR AND DIGITAL INTEGRATOR
(ADE5169/ADE5569 ONLY)
The di/dt sensor, a feature available for the ADE5169/ADE5569,
detects changes in the magnetic field caused by ac currents.
Figure 50 shows the principle of a di/dt current sensor.

Figure 50. Principle of a di/dt Current Sensor
The flux density of a magnetic field induced by a current is directly
proportional to the magnitude of the current. The changes in the
magnetic flux density passing through a conductor loop generate
an electromotive force (EMF) between the two ends of the loop.
The EMF is a voltage signal that is proportional to the di/dt of the
current. The voltage output from the di/dt current sensor is deter-
mined by the mutual inductance between the current-carrying
conductor and the di/dt sensor. The current signal needs to be
recovered from the di/dt signal before it can be used. An integrator
is, therefore, necessary to restore the signal to its original form.
The ADE5169/ADE5569 has a built-in digital integrator to recover
the current signal from the di/dt sensor. The digital integrator
on the current channel is switched off by default when the
ADE5169/ADE5569 is powered up. Setting the INTE bit (Bit 5)
in the MODE1 register (Address 0x0B) turns on the integrator.
