AMC130M02: Method for converting single end into differential signal

Part Number: AMC130M02

Tool/software:

Hi All,

I would like to know how to convert single end to differential signal.

Is it possible to exchange information properly if I use AD2 fixed to GND? Or is there another good way?

Input voltage of AD1 and AD2 will be in the range of 0V to 1.0V.

Is it better to use differential amplifier or inversion buffer?

If there is a best way, please let me know.

Best Regards,

Ryusuke

    Hi Ryusuke,

    This part has a SPI interface to send the measurement data over.  It's expected that the MCU would communicate with the device over SPI to configure the device and read data from it.  
    We currently have Isolated amplifiers that provide differential output and are in the process of releasing devices with single ended outputs if you are interested in an analog output.  You can also reference this app note to convert from differential to single ended.

    Thanks

    Hi Saleh,

    My question was not good. I am sorry.

    Since the signal input to AMC130M02 is single-ended, I asked how to convert the single-ended signal to differential.

    The application note describes how to convert the differential signal output of AMC130M02 to single-ended.

    Should the input side be converted in the same way?(One connected, the other floating or connecting GND, etc.)

    Best Regards,

    Ryusuke
