Hi. 

Happy new year !

I'd like to use one of ST compass + accelerometer chip (2 in 1) for implementing with one of analog device gyroscope in Kalman filter. 

Which sensor do you offer?  what is the criteria of choosing the right sensor? i need most accurate and stable one.

(only 1.8V Vcc).

The criteria really depends on your application and requirements, it could be: current consumption, FS ranges/sensitivity, available output data rates, package size, noise, ...
