ISO1541: iso1541

Part Number: ISO1541

We are using the ISO1541QDRQ1 in a new design. The datasheet text states that 100n bypassing is all that is needed on the supply pins, yet the application notes specifically call for a 10u capacitor within 2mm of the supply pins. Is this a typo and meant to say 100n within 2mm of the supply pins, or do we really need 10u caps?

    Hi John,

    100nF of capacitance should be sufficient for decoupling capacitors at both VCC1 and VCC2 within 2mm distance, the 10µF should be a typo. You can use 100nF and you shouldn't have any issues with that.
