I wondered which has a better noise peformance between analogoutput type and digital outputtype.
According to the datasheet ADXL202(analog output type),
The output noise is 1.4mg_rms@100Hz from Table 7.
On the other hand, ditital output type, ADXL345's noise peformance is 0.75LSBrms LSB@100Hz from the datasheet.
I'm not sure that which is a better spec between 0.75LSBrms and 1.4mg_rms.
Please tell me how to compare [mgrms] and [LSBrms].
