ADE7116/ADE7156/ADE7166/ADE7169/ADE7566/ADE7569
The ADE7169/ADE7569 have 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 ADE7169/ADE7569 are powered up. Setting the INTE bit
(Bit 5) in the MODE1 register (Address 0x0B) turns on the
integrator. Figure 51 to Figure 54 show the gain and phase
response of the digital integrator.

Note that the integrator has a ?20 dB/dec attenuation and an
approximately ?90° phase shift. When combined with a di/dt
sensor, the resulting magnitude and phase response should be a

significant high frequency noise. Therefore, a more effective
antialiasing filter is needed to avoid noise due to aliasing (see
the Antialiasing Filter section).
When the digital integrator is switched off, the ADE7169/ADE7569
can be used directly with a conventional current sensor, such as a
current transformer (CT), or with a low resistance current
shunt.
