As you correctly stated, at an ODR of 100Hz and OSR = 7, 16 samples are gathered (the sampling rate is actually 1600Hz) and averaged. Table 203 summarizes all eight oversampling options which trade-off between resolution and current consumption at varying sample rates.</P><P></P><P><span class="lia-inline-image-display-wrapper" image-alt="Table 203.JPG"><img src="https://community.nxp.com/t5/image/serverpage/image-id/30099i72C6056FC6579D6A/image-size/large?v=v2&amp;px=999" role="button" title="Table 203.JPG" alt="Table 203.JPG" /></span></P><P></P><P>Best regards,</P><P>Tomas</P></BODY></HTML> Thu, 12 Oct 2017 14:12:38 GMT https://community.nxp.com/t5/Sensors/Oversampling-FXOS8700CQ/m-p/703010#M4537 TomasVaverka 2017-10-12T14:12:38Z
