I am using ade7880 for energy metering.
Following 2 images from ad 7880 evaluation shows the phase voltage input structure.
But i have a doubt how this can be used to decrease the input line voltage to 0.5V.
Thanks and Regards
Yes. It is a typo where it says 1 ohm in the voltage channel input. It was meant to be 1 Mohm. It will be corrected in the next revision of the document. The evaluation board schematic at the end of the document has the correct values used.
Actually there is a mistake in the ADE 7880 evaluation board User Guide page no.5.The value of R26 resistor cannot be 1 ohm to act as a voltage attenuator. For evaluation board it is 1 Mohms.
Somebody please confirm.
