    Hello Du,

    Thank you for your post.

    If you only require one SDO pin, please use one of the two Single-SDO Mode settings. The ADS7853 offers a 32-CLK Single-SDO Mode and a 16-CLK Single-SDO Mode. 

    When using the Single-SDO modes, the SDO_B pin will be tri-state (i.e. high-impedance). You can leave the the SDO_B pin floating.

    Best regards,
