FXLN83xxQ from NXP 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 3 x 3 x 1 mm 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 0.75 V, irrespective of the VDD 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.
