Hi
I am new to Ti ADC part, I have EVM board with ADS1278 on it. For the first time i connected the board to PC and ran the ADC pro software. I configured the board as per the default setting mention in EVM datasheet. I ran the system with ADC input pin open. What i observed was the ADC channel values (1-8) were FFFFcde or AED. Here i did not understand the byte formation of the resultant value of each ADC channel.
In second hardware connection i connected channel 5 (positive) to AGND.
Then connected the same to VCC(1.8). In both configuration the results were unstable.In boath cases channel 5(negative) was open.
Let me know how to verify the EVM board with ADC input and mapping it with the DC source for example FFF = 1.8volt
Regards,
Sahil
