Allegro ACS71020 power monitoring IC noise issue
« on: June 12, 2026, 09:39:35 pm »
I have an ethernet chip on the same circuit as an Allegro Power monitoring IC which is completely throwing off the readings. Any suggestions?

Can't say if this is what's going on with your circuit, but I've used acs711 sensors before and they are incredibly sensitive to external magnetic fields, so if you run another high current trace near it, the field will couple into the sensor and jack up the measurement.
