ADC_CAL0 and ADC_CAL1

Other Parts Discussed in Thread: CONTROLSUITE

I have a question about adc of f28377d board.

According to the datasheet and pinout pdf of f28377d board there is 12 "16-bit differential adc" input on the board and I tried every one of them however the ADC-C0 and ADC-C1 pair doesn't work. (the rest are ok.)

Also the name of this pair is different on a pinout pdf. (ADC_CAL0 ADC_CAL1) Why is that ? Could the application of those pins be different?

thanks a lot

Hi Fatih,

The name of ADC_CAL0 and ADC_CAL1 got changed to ADCIN14 and ADCIN15 at some point.
(partially to avoid potential confusion like what you have had here :) )

Can you let me know where you found the names "ADC_CAL0" and "ADC_CAL1"? We will then revise that document to use the new naming.

Thank you,
Brett

the name of the document is "F2837x_180controlCARD_R1_1_SCH_05Dec2013" but I have no şdea where it is found.

Then where is the 12th adc? Which pins I will use on the board?

Could you give me the link for the revised pinout?

Thank you again.

Hi fatih kara,

In the latest release of controlSUITE you will find the attached.

What do you mean by the 12th ADC? In the attached you will find that there are 24 single-ended ADC inputs (or 12 differential inputs).

Please note that ADCIN14 and ADCIN15 go to all 4 ADC modules (A,B,C & D) as documented in the TRM.

Thank you,
Brett
