Problems Using Audio Chip Instead of ADC / DAC?

I have a question about using the ADAU1761 chip.

All I need is precision ADC / DAC functionality.


This chip has two 24bit ADC / DACs, so I selected it. 

I like the sampling rate of 48Khz, and I like ADC / DAC on one chip.


I'm talking about this audio chip. You need to make sure that you can use a place in the precision sensor.


The circuit I'm designing is :

Sensor -> amplifier -> ADC -> Signal Processing -> DAC output


You have to have the precision of microvolts. Is there any problem?


If anyone knows, let me know.
