Xtrinsic FXLN83xxQ 3-Axis Low-
Power Analog-Output Accelerometer
FXLN83xxQ is a family of 3-axis, low-power, low-g, analog-
output accelerometers that consist of an acceleration sensor
along with a CMOS signal conditioning and control ASIC in a
3x3x1mm QFN package. The analog outputs for the X, Y, and Z
axes are internally compensated for zero-g offset and sensitivity,
and then buffered to the output pads. The outputs have a fixed
zero-g offset of 0.75V, irrespective of the V
DD
supply voltage.
The bandwidth of the output signal for each axis may be
independently adjusted using external capacitors. The host can
place the FXLN83xxQ into a low-current shutdown mode to
conserve power.
