Datasheet ADXL335 (Analog Devices)

Small, Low Power, 3-Axis ±3 g Accelerometer ADXL335 FEATURES GENERAL DESCRIPTION 3-axis sensing
The ADXL335 is a small, thin, low power, complete 3-axis accel-
Small, low profile package
erometer with signal conditioned voltage outputs. The product
4 mm × 4 mm × 1.45 mm LFCSP
measures acceleration with a minimum full-scale range of ±3 g.
Low power : 350 μA (typical)
It can measure the static acceleration of gravity in tilt-sensing
Single-supply operation: 1.8 V to 3.6 V
applications, as well as dynamic acceleration resulting from
10,000 g shock survival
motion, shock, or vibration.
Excellent temperature stability
The user selects the bandwidth of the accelerometer using the
BW adjustment with a single capacitor per axis
CX, CY, and CZ capacitors at the XOUT, YOUT, and ZOUT pins.
RoHS/WEEE lead-free compliant
Bandwidths can be selected to suit the application, with a

range of 0.5 Hz to 1600 Hz for the X and Y axes, and a range
APPLICATIONS
of 0.5 Hz to 550 Hz for the Z axis.
Cost sensitive, low power, motion- and tilt-sensing
The ADXL335 is available in a small, low profile, 4 mm ×
applications
