ADXL150/ADXL250 DEVICE BANDWIDTH VS. MEASUREMENT RESOLUTION Although an accelerometer is usually specified according to its full-scale g level, the limiting resolution of the device, i.e., its minimum discernible input level, is extremely important when measuring low g accelerations. 100m g ...

MINIMIZING EMI/RFI The architecture of the ADXL150/ADXL250, and its use of synchronous demodulation, makes the device immune to most electromagnetic (EMI) and radio frequency (RFI) interference. The use of synchronous demodulation allows the circuit to reject all signals except those ...
