Recently I use ADXL375, I'm communicating with the ADXL375 over SPI (4 wire) using a TMS320 F28069 texas intrumentDSP.
ODR = 3200Hz.
First : i found two offset adjustments in datasheet: p21 register 1E,1F, 20 scale factor 0.192 g/LSB
p28 OFFSET CALIBRATION 1.56 g/LSB (but i thinks is mistake 0.156 g/LSB)
what is the right factors ?
Two : I've a lot of noise, the noise earth gravity sample measured +/- 3g !!! (but sensitivity is good)
How can limit/lessen the noise ?
The average are 20.0256 LSB ===> 0.94 g
