Question Can I power any devices off Vddiso? Answer No. Do not connect external active circuitry to this pin. Decouple this pin
with a 10 μF capacitor in parallel with a ceramic 100 nF capacitor using…
Question Can I use a permanent magnet to influence the behavior of the ADE7912/ADE7913
or ADE7932/ADE7933? Answer The devices integrate chip scale air transformers that are not affected by
external…
Question Can I use an external voltage reference of the ADE7912/ADE7913 or
ADE7932/ADE7933? Answer No because the isolated dc to dc converter integrated into the devices was not
designed to support…
Question My application must use ADE7912, to measure AC and DC voltage. Can you confirmthat the A/D converter works also with DC input voltage ? Answer Yes, you can measure positive and negative DC voltages…
Question I would like to monitor an 800V battery. Is this possible? Answer No. The maximum continuous dc working voltage for a 50-year life is 600V.
Voltages above this will degrade the lifetime significantly…
Question Is the provided data for surge isolation voltage on page 8 of datasheet (rev.
PrJ) meant to be with or without an extra Y capacitor? Is there an extra
Y-capacitor needed for burst/surge performance…
Question What is the lowest shunt value I can use with these ADE7912/ADE7913 or
ADE7932/ADE7933? Answer These devices have been designed to be used with shunt values of at least 180
µΩ. Because the…
Question What three phase systems are supported by the ADE7912/ADE7913 or
ADE7932/ADE7933? Answer The isolation technology used inside the ADE7912/ADE7913 or ADE7932/ADE7933
guarantees that for 50…
