    Single ended Delsig ADC producing output of 0.209 V when input is 0

      I am working on PSOC 5LP kit. I am trying to implement an ADC , first I followed this link (https://eewiki.net/display/microcontroller/Utilizing+Analog+Peripherals+on+the+PSOC+5LP). But in this when i am working on Delsig ADC, even though the input is zero i am getting an output of 0.29V. I couldn't understand the reason behind that (but i thought this is because of Vref). SAR ADC is working fine. What is the reason and how to solve it. 

         

      Thanks
