AMC1311-Q1: Higher accuracy recommendation

Part Number: AMC1311-Q1
Other Parts Discussed in Thread: AMC1211-Q1, , AMC3330-Q1, AMC1351-Q1

Dear team,

Below is our AMC1311-Q1/AMC1211-Q1 accuracy. Do we have other device with better accuracy(analog signal)? I noticed that the accuracy is almost same for voltage sensing devices in Current sense device has better accuracy.

Thanks & Best Regards,


  • Hi Sherry,

    It looks like you may be referencing an older version of the datasheet:

    Is there a particular accuracy parameter that is of concern? Do you know the overall accuracy target for the measurement? 

    The magnitude of the voltage to be measured and the planned calibration (offset, or gain and offset) have a large impact on which device performs the best. AMC1351-Q1 or AMC3330-Q1 are good devices to take a look at too. We have an AMC Voltage sensing excel accuracy calculator that may be able to help:

    The offset error parameter is input referred, hence why the current sensing devices with a smaller input voltage range appear to have better accuracy compared to the voltage sensing devices.
