ADXL335 is a small, thin, low power, complete 3-axis accelerometer with signal conditioned voltage outputs. The product measures acceleration with a minimum full-scale range of ±3 g. It can measure the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration in motion-sensing applications
The ADXL335 accelerometer provides a compact 3‑axis measurement solution with a minimum full‑scale range of +3 g and a low‑power supply requirement of 1.8 V to 3.6 V. It includes a polysilicon surface‑micromachined sensor, signal‑conditioning circuitry and analog voltage outputs that are ratiometric to the supply voltage.
The datasheet covers features, electrical specifications, pin configuration, bandwidth selection, self‑test operation, mechanical layout recommendations and typical application examples such as mobile devices, gaming systems and motion‑sensing equipment.

The ADXL335 operates from 1.8 V to 3.6 V supply voltage.
Bandwidth is set by adding external capacitors Cx, Cy and Cz to the Xout, Yout and Zout pins; the 3 dB bandwidth follows F = 1/(2·π·R·C).
Typical supply current is 350 µA at a 3 V supply.
The device can survive up to 10,000 g shock on any axis.
