Simple Inclinometer Accuracy?

I require a simple inclinometer where the chip is mounted vertically to measure a tilt angle of +/- 20 degrees in the X and Y planes.

The Accuracy needs to be +/- 0.5 degrees. Since the chip is mounted vertically I assume I will need a 3-axis accelerometer.

I am considering using the FXLS8471Q however referring to the data sheet on Page 24 it says: “All Angles are accurate to +/- 2 degrees”
