ad7654astz least bits problems

Hello.

My 16-bit ADC7654 shows all zeroes in last bits after each conversion.

In conversion only about 5 bits changes normally, while other less significant bits stays zeroes. Also in log file i can see values with only zeroes in output. Is it normal functioning taking into account that voltage on vref and analog inputs applied directly from voltage source (without reference and input drivers).
