I need to know what is the maximum current that support analog input channels of red Pitaya, I read that support 3.5 volts, but have not found anything about the current.

The RF inputs have a high impedance (1MOhm / 10pF), which means they will draw very little current from the signal source.
The slow analog inputs have an impedance of ~35kOhm, according to the published schematics
. So they'll draw 100µA at full scale input.
