PSoC3 DELSIG ADC cofigured as single ended and input range Vssa to Vdda and 8bit res gives near Full Scale reading when input is 2.5v (Cy8CKIT-001 is set to 5v and all VddIO jumpers are set to Vdd. The Vref is set at Vdda/4 so... 2.5v and is not changable.... BUT for an input range of Vssa to Vdda shouldn't Vref be Vdda/2 instead of Vdda/4? Why am I unable to change Vref? Why should it be Vref/4 instead of Vref/2? What am I missing? Thanks

Will now try some Level Shift experiments.
