RFSoC adjust ADC full-scale range

Jump to solution

Is there any way to adjust ADC full scale range? I believe it can't be done internally; can it be done externally (not by increasing LNA gain but by changing ADC reference voltage/current)?

The data converter power supply levels and quality should be adhered to. It is not allowed to deviate from these supply values. 

The Input power for full scale is fixed as @karnanl says.

Hello @lalit_nps 

Your understanding should be correct ADC full-range isn't adjustable. It should be fixed 1dBm as mentioned in datasheet.

ADC power-rail requirement is very strict, I dont think there is not much room for adjustment here.
