  • RE: CCS/TM4C1294NCPDT: AMC7820, SPI

    Resolved
    I don't have an example of interfacing to the AMC7820, but looking at the datasheet I think you need to use Freescale SPI Frame Format with SPO=0 and SPH=1. Each read or write requires two 16-bit transfers with the slave select staying low between the…

  • AMC7820 external reference voltage range

    Resolved
    Hi The voltage range for external reference is 2.45V to 2.55V, mentioned in the datasheet. Analog input range is from 0 to 2Vref. So is it possible to provide an external Vref say 3V?

  • RE: AMC7820 adc interfacing

    Hi Parag, Welcome to our community! Can you describe how you have the AMC7820EVM connected to your micro controller? Basically let us know how you are wired into J2. If you can provide a screen shot of your SPI interface, that would be useful as well…
