Hi All,
I am planning to measure AC load current using ACS718. The output of ACS718 is sine with 2.5 volt positive offset. My microcontroller ADC positive reference is 3.3V. I am facing difficulty in reading the ACS718 output using microcontroller.
Please help me to solve this issue.
My circuit is attached below
