    Hello Martin,

    Thank you for your post.

    The SDO pin does not need to be modeled. The intention of the TINA-TI Transient Spice models for our ADCs is to mimic the behavior of the switch-capacitator front-end sampling network. The outputs of this model are the sampled voltages on AINP and AINM. Customers can assume that the digital output of the ADC will be the binary equivalent of the differential sampled voltage (AINP_SAMPLED - AINM_SAMPLED).

    Regards,
