I am trying to interface Acs712 current sensor IC with an energy metering Ic(Ade7858),there are two problems am currently facing.
1) The energy metering Ic takes in bipolar input (± 0.5 V) which is designed to use current transformer but the output from Acs712 is uni-polar which is (0-5v).
2)I tried using the schematic above to convert uni-polar (0-5v) to bipolar(± 0.5 V) which gives a single ended output but the inputs for the Ade7878(energy metering IC) is differential input as shown in the below diagram from datasheet.
kindly suggest me if I should go with a single ended to differential converter if am not wrong or is there a better cost effective solution.
