Hi, I have a couple of ACS711EX -31A;+31A current sensors. I connected them like in the wiring diagram on your website. Supply voltage is 5V. When there is no current, output voltage is stable 2.5V. When I apply +2A of current, VOUT goes down to 1.6V. When I apply -2A (reverse direction), VOUT goes down to 1.3V. I even try connecting 1nF and 15kohm between VOUT and GND (as said in datasheet). This testing was done on my workdesk, inside my flat, so no heavy EM environment expected.
I tested it also with 3.3V and same thing happens - to large of a voltage drop for only 2A of current.
Sensors were ordered from HobbyTronics, IC chip number is 711 1341 662M.
Can you please help me. What am I doing wrong?
Thank you in advance!
