[MSP432] Confirm whether there is the algorithm for measuring the voltage by 24ch - 14bit ADC

Hi TI Experts,

Please let me confirm the following question.
[Question]
Does TI have a algorithm to measure the input voltage by 24ch-14bit ADC with high accuracy as possible?
It seems that the ADC14 function on MSP432 is too rich again the operation frequency is 48MHz. My customer concerned that it will be able to measure this voltage with high accuracy even though they will use the 24ch.

If you have any questions, please let me know.

Best regards.

    Hi Kaka!

    I think, I do not understand your question correctly. Could you specify your problem?

    There are code examples you can download here. They include different examples on how to use the ADC14 module:

    • msp432p401_adc14_01                           ADC14, Sample A1, AVcc Ref, Set P1.0 if A1 > 0.5*Avcc
    • msp432p401_adc14_03                           ADC14, Sample A2-A3 Differential,Set P1.0 if i/p> 1V
    • msp432p401_adc14_05                           ADC14, Using an External Reference
    • msp432p401_adc14_06                           ADC14, Repeated Sequence of Conversions
    • msp432p401_adc14_10                           ADC14, Sample A12 Temp and Convert to oC and oF
    • msp432p401_adc14_21                           ADC14, Window Comparator, 2.5V ref

    Of course these examples will not perfectly fit for your specific application, but they are a good point to start from.

    Hi Dennis,

    We do not have any issue for this function. Also I know that TI have some sample codes for this device including the ADC14.
    To measure the input voltage with high resolution, they think that it needs to prepare the algorithm to reduce the noise.

    If you have any questions, please let me know.
    Best regards.
