TMS320F28335: Support on ADC Channels

Chaya Kiranmayee Reddy Gaddam

Hi,

I have a doubt that can we give an voltage reference from TMS320F28335 board internally to ADC channels in TMS320F28335 and the voltage reference should shift for all ADC channels.

Thanks & Regards,

Hi,

I do not understand your question, are you worried that the voltage reference will be unstable? Could you please clarify?

Best Regards,

Hi Chaya,

It is not possible to use 3.3V as a reference on this device. Could you step down your input voltage or would you be willing to consider a newer C2000 device?
