ADE7762
ANALOG INPUTS
CURRENT CHANNELS
The voltage outputs from the current transducers are connected
to the ADE7762 current channels, which are fully differential
voltage inputs. IAP, IBP, and ICP are the positive inputs for IAN,
IBN, and ICN, respectively.
The maximum peak differential signal on the current channel
should be less than ±500 mV (353 mV rms for a pure sinusoidal
signal) for the specified operation.
The maximum signal levels on IAP and IAN are shown in
Figure 14. The maximum differential voltage between IAP
and IAN is ±500 mV. The differential voltage signal on the
inputs must be referenced to a common mode, for example,
AGND. The maximum common-mode signal shown in
Figure 14 is ±25 mV.

VOLTAGE CHANNELS
The output of the line voltage transducer is connected to the
voltage inputs of the ADE7762. Voltage channels are pseudo-
differential voltage inputs. VAP, VBP, and VCP are the positive
inputs with respect to VN.
The maximum peak differential signal on the voltage channel is
±500 mV (353 mV rms for a pure sinusoidal signal) for a speci-
fied operation.
Figure 15 illustrates the maximum signal levels that can be
connected to the ADE7762 voltage channels.
Voltage channels must be driven from a common-mode voltage,
that is, the differential voltage signal on the input must be refer-
enced to a common mode (usually AGND). The analog inputs
of the ADE7762 can be driven with common-mode voltages of
up to 25 mV with respect to AGND. However, best results are
achieved using a common mode equal to AGND.
