ADC in DE-10 Nano

[Mohitgarg]

Hi when I use ADC at 20MHZ clock frequency there is offset comes means ADC is providing current to the board when I use 500KHZ it decreases how to correct it I want to use more sampling frequency

Hi Mohitgarg,

Is the "ADC" you mentioned the separate ADC device on DE-10 Nano or the ADC on FPGA?

Thanks & Regards,

Hi Mohit garg,

I checked the User Manual of DE-10 Nano board. LTC2308 seems to be a general-use ADC.

According to your question, did you use it to test the system current or FPGA current? Or what is your usage with it?

Thanks & Regards,
