AD9204 sampling single ended DC signal, how to connect the analog front end

I have a design that requires the use of AD9204 to sample a single ended DC signal, do not know how to connect analog front end circuit.


The current design is to connect the AD9204 analog input AIN- to the GND, and the single ended DC signal is connected to the AIN+.


The input DC voltage range is 0V~1V. I don't know whether this connection can be properly sampled.


If it can't, I need to how connect AIN- and AIN+. (due to power constraints, can not use the differential amplifier)
