What is the recommendation for connecting the NC pins of the ADE7816? In the datasheet (Rev A) the recommendation is to leave them floating, however recent posts referring to other energy metering chips suggest connecting them to GND, along with the EPAD.
What is the preferred approach? Thanks.
Thank you, we recommend that you do not leave them floating and have them connected to the ground. We are working on another rev for the datasheet about this concern.
THank you very much.
Thanks you. Just to clarify, you are recommending ALL NC pins connected to GND? Per the current datasheet pins 33 and 34 state specifically NOT to tie them to GND. Can you please clarify what the recommended practice is for these pins.
1, 10, 11, 20,21, 30, 31, 40NC No Connect. These pins are not connected internally and should be left floating.
33, 34 NC No Connect. These pins should be left floating. Do not connect to GND.
In our revised datasheet (soon to publish), the pins 33 and 34 are specialized NC pins that MUST be left floating. Only the first set of pins 1, 10, 11, 20, 21, 30, 31, 40 and EPAD must be tied to ground.
