ADXL326 FEATURES GENERAL DESCRIPTION 3-axis sensing The ADXL326 is a small, low power, complete 3-axis Small, low profile package accelerometer with signal conditioned voltage outputs. The 4 mm × 4 mm × 1.45 mm LFCSP product measures acceleration with a minimum full-scale range Low power: 350 μA typical of ±16 g. It can measure the static acceleration of gravity in tilt- Single-supply operation: 1.8 V to 3.6 V sensing applications, as well as dynamic acceleration, resulting 10,000 g shock survival from motion, shock, or vibration. Excellent temperature stability
The user selects the bandwidth of the accelerometer using
Bandwidth adjustment with a single capacitor per axis
the CX, CY, and CZ capacitors at the XOUT, YOUT, and ZOUT pins.
Ro HS/WEEE lead-free compliant
Bandwidths can be selected to suit the application with a range of 0.5 Hz to 1600 Hz for X and Y axes and a range of APPLICATIONS 0.5 Hz to 550 Hz for the Z axis. Cost-sensitive, low power, motion- and tilt-sensing applications The ADXL326 is available in a small, low profile, 4 mm ×
