Hello, I have implemented in single ended mode the ADC10040 as described in page 20. I am observing that the digital output D0-D9 is stuck to 0 until the Vin signal reach around 350mV. Then upper 350mV, the output seems to start to decode. I have joined the VCOM to my Vin- pin as in your example.
My signal is a constant voltage for this debug. Have you any ideas because I need to sample from 0V to full scale= 2V ( IRS=1) ? Best regards
