AD7984Production
The AD7984 is an 18-bit, successive approximation, analog-to-digital converter (ADC) that operates from a single power supply, VDD. It contains a low power...

Thanks for your query. Unfortunately the answer is no, the AD7984 requires the input common mode voltage of the IN+ and IN- pins be nominally VREF/2. For example, if VREF = 5V, then the common mode voltage must be 2.5V at all times for the ADC to be functional.
I recommend looking at either the AD4002, AD4006 or AD7980 as a replacement for the AD7984 here. The AD4002/AD4006 are 18-bit, single-ended ADCs that you could connect the IN- input to GND. The AD7980 is also single-ended, but is only 16-bits. All of these ADCs are pin-compatible to the AD7984.
