CN0349 power consumption

Hi, I understood that CN0349 is running on 3.3v. Anyone knows the current needed?

Thank you

  • The CN0349 hardware is no longer available for purchase.

    However, the power dissipation can be calculated by adding up the contributions of the various components as taken from their respective data sheets:

    AD5934 @ 3.3V: 15mA

    AD8606 @ 3.3V: 2.8mA

    ADG715 @ 3.3V: 20uA

    FXO-HC536R-1 crystal oscillator @ 3.3V: 32mA

    ADuM1250 @3.3V: 3mA/side, total = 6mA

    Total not including ADuM5000:  55.82mA

    ADuM5000 with 55.82mA load:

    Efficiency of ADuM5000 supply is 28% and it must supply 55.82mA to the load.

    Therefore you must supply 55.82/0.28 = 200mA to the ADuM5000 to get 55.82mA out.

    The total power dissipation of the circuit is therefore approximately 200mA.
