  • RE: DAC161S997: Typical application for 4-20mA output

    Resolved
    Hi Zhongwen, It should work if you use and LDO to provide VA from the loop power supply, but again this will be the loop powered configuration where the power supply is in series with the loop. You would not be able to have a separate loop driving just…
