DS15EA101: Vin Common Mode Voltage

Part Number: DS15EA101

Hello,

Does the DS15EA101 provide its own common mode bias?  The examples in its data sheet show AC coupling of the differential input, but not any external DC bias on the DS15EA101 inputs (input side of the decoupling capacitor).  What will happen if the DS15EA101 has floating inputs?

Thanks for any help you can give,


Rob Curtis

  • The DS15EA101 inputs are internally biased and AC coupling is required.

    If there is no signal on the DS15EA101 inputs, internal circuitry will detect this condition, LOS status output will be active high, outputs will be disabled.

    Regards,

    Lee
