AMC1301: AMC1301 Design problem

Prodigy 50 points

Part Number: AMC1301
Other Parts Discussed in Thread: AMC3330

Tool/software:

I’m using the AMC1301 in my design—does the current layout have any issues? Are there any improvements I can make? Also, are VINP and VINN impedance-matched in this design? Based on the current layout, why is there still some noise in my output waveform?

    Hi Lin, 

    I would suggest using a product intended for voltage sensing such as AMC3330 as opposed to AMC1301, intended for current sensing. 

    There is a small amount of noise in the measurement, which is likely expected for these products.
