Tool/software:

Dear sir or madam

I have some question about AMC1202 application

1. whether the AMC1202 is the bidirectional current sensor amplifier?

   but form the datasheet, the AMC1202 INP and INN voltage range as the below show:

   if use the high side application, the INP and INN voltage must be over than the datasheet max value.

2. how to calculate the AMC1202 error, from the below excel, I don ‘t knows the detail calculation step, how to calculate the final error.

    Hi Qiaoqin,

    Thank you for your questions. What application are you using the AMC1202 for? 

    1. The input range of the device is +/-50mV. Please follow the recommended operating conditions for supply and input values. 

    2. The help and directions tab give more information on how the calculator works. The intermediary cells also trail where the final results are calculated from. 

    Please let me know if I can help with anything else!

    Best regards,

    Eva

    hi Evea

    1. Thank you for your reply, but I still don't know how to use ACM1202 if it is used for current high-side detection?

    2. The table can be used to obtain the output error based on the input, but I want to know how it is calculated step by step, because this Excel table cannot tell how it is calculated step by step. I want to know the specific calculation steps, thank you.

    Hi Qiaoqin,

    1. What is the application? What are the requirements for the system you are working on? You can use the AMC1202 for high-side detection, but you should not exceed the recommended operating conditions. If this part does not satisfy your project's requirements in some way, I could help suggest an alternative part as well!

    2. These calculations are not something we publicly share. Are you looking to compare these calculations to your own? 

    Best regards,

    Eva
