ADS42JB49: ADS42JB49 Single end Input

HENRY JUNG
Expert 2030 points
Part Number: ADS42JB49

Dears.

We are in the circuit design of ADS42JB49

We need a guide to design the input of the ADS42JB49 as single-ended.

We are need to Balun and Impedance guide information.

Thank you.

    Henry,

    Why are you asking for balun information if you are going to drive this ADC single-ended?

    Regards,

    Jim

    Henry,

    This part will not work in single-ended mode. See the schematic attached for using a transformer input example.

    DEAR.JIM

    Difference inputs AINP and AINM.

    AINM is DNI. It is not input as AINM.

    Does it work by receiving only AINP?

    I understand so in the EVM circuit.

    Since I was input to AINP in EVM circuit and operated, I understood with Single-End.

    I am considering receiving input from AINP.

    Changing Balun, Impedance is possible.

    Thank you.

    Henry,

    I am having trouble understanding you. Please send a block diagram or schematic. If you can only provide a single-ended input to the ADC, you will have to use another device. If this is the case, let me know the sample rate, the IF rate, and number of bits and I will see if I can suggest another part to use.

    Regards,

    Jim
