ISO1050: power supply ripple index

Joe Ji

Part Number: ISO1050


Hi team

My customer Lango will qualify the ISO1050 in their device library. there is one index not shown in datasheet but necessary for the qualification test. 

Is there the voltage supply ripple limitation of Vcc1 and Vcc2?

Thank you

Joe

    Hi Joe,

    Thanks for reaching out.

    It is not common to spec the ripple voltage supported by digital device like digital isolators, MCU or buffers rather this is a critical spec for analog devices like ADC, amplifiers and others. Hence, we don't have a voltage ripple spec defined for VCC of ISO1050 but we do expect most ripple voltages not be an issue as long as they are within device recommended operating conditions.

    Please let me know what is the ripple voltage that customer is expected on the supply voltages so that I can better comment if that is going to be a problem for ISO1050. Thanks.
