Is there an example of how to connect the ADE7933 with current transformers?
Thank you

The ADE7978, the ADE7933/ADE7932, and ADE7923 form a
chipset dedicated to measuring 3-phase electrical energy using
shunts as current sensors.

Hi Fausto Bartra,
The ADE7933 is an isolated ADC most typically meant for use with a shunt current sensor. If you are using a current transformer then isolation is already present in the transformer.
Could you tell me more about the application? Maybe there is a more appropriate metering IC to choose from with use with CT's. Do you need to use CT's over shunts? Is this a 3-phase application?
The maximum input level on the current channel is +/-31.25mV Peak, therefore a small burden would have to be chosen to not over range this input.
