While I will be using ADE9078 for 3 phase system power measurement, I would like to monitor a specific DC power supply on (INP, INN) inputs, with a shunt implementation to meet the ±0.5V limits.
- Is it possible to connect directly INN to GND ? (e.g. bypass the 1k/22n filter)
- What registers have to be set ?
Thanks for help,
The High-pass filter is enabled so any dc measurement is not possible on the neutral. If you disable the high pass it will be disabled on all channels and power measurements will suffer.
The anti-alias should still be used.
ok, then unused ADC will have to remain unused...
Thanks anyway for fast answer
