Working Principles

The AMC1301QDWVQ1 utilizes a delta-sigma modulator to convert the analog input current into a digital representation. The modulator operates by oversampling the input signal and using a feedback loop to continuously adjust the output based on the difference between the input and the desired output. This digital representation is then filtered to remove noise and provide a high-resolution measurement of the input current.
