This is with reference to the two figures on the datasheet at http://www.analog.com/static/imported-files/user_guides/EVAL-ADXL375_User_Guide.pdf
There is a CS' (i.e. CS with a bar)pin on the ADXL375 pin out. It should be connected to VDD for I2C interface.
However, on the ADXL375Z breakout board, tehre is CS (without a bar). Is it the same as the CS' (CS wityh a bar) pin on the ADXL375 chip? Should we connect the CS (without a bar) pin on the ADXL375Z to the ground or to VDD?
