TMDSDOCK28379D: evaluating 4 ADCs simultaneously

Part Number: TMS320F28379D
Other Parts Discussed in Thread: TMDSDOCK28379D

Hi,

Good day.

Our customer has this inquiry about the. Can you please help us? Thanks.

I would like to use the TMS320F28379D in a custom board for sensing application. In order to do so, we were thinking to acquire the TMDSDOCK28379D F28379D Delfino Experimenter kit to evaluate the characteristics of the 4 ADCs present in the microcontroller, crucial components for our application.
Is it possible with this kit to evaluate the 4 ADCs characteristics while they acquire data simultaneously? What we would like to do is to send a differential input for every ADC and evaluate them.


Regards,

Cedrick

    Hello E2E,

    Our customer would like to use the TMS320F28379D in a custom board for sensing applications. They would like to acquire the TMDSDOCK28379D F28379D Delfino Experimenter kit to evaluate the characteristics of the 4 ADCs present in the microcontroller. Is it possible with this kit to evaluate the 4 ADCs characteristics while they acquire data simultaneously? Also, are there physically enough inputs in the docking station/controlCARD that will lead to the differential inputs of the 4 ADCs? What they would like to do is to send a differential input or at least a single-ended one) for every ADC and evaluate them. 

    Is it actually possible or there are any alternatives to do so?

    Regards,
    Carlo

    Cedrick,

    The implementation on the controlCARD supports what the customer wants to do, in terms of both available ADC channels as well as the reference network.  From above differential input comment, they will be using the ADC in 16-bit mode.  At this bit level, the signal integrity if very important and the controlCARD/dock being generic does not have any amplifiers on the board.  If the customer has a source that is 16-bit accurate with drivers then it should be OK, but wanted to make this point. 

    We have some application notes for this to help the customer better understand the requirements/simulation, one is https://www.ti.com/lit/spracz0 there should be links to others in that app note as well.

    I know that we also use this reference board to conduct tests on the ADC as well https://www.ti.com/tool/PSIEVM

    Best,
