FEATURES

GENERAL DESCRIPTION

Small and thin

4 mm × 4 mm × 1.45 mm LFCSP package

2 mg resolution at 60 Hz

Wide supply voltage range: 2.4 V to 6 V

Low power: 340 μA at V_S= 2.4 V (typ)

Good zero g bias stability

The ADXL322 is a small, thin, low power, complete, dual-axis

accelerometer with signal conditioned voltage outputs, which

are all on a single monolithic IC. The product measures accel-

eration with a full-scale range of 2 g (typical). It can also

measure both dynamic acceleration (vibration) and static

acceleration (gravity).

Good sensitivity accuracy

The ADXL322’s typical noise floor is 220 μg/√Hz, which allows

signals below 2 mg to be resolved in tilt-sensing applications

using narrow bandwidths (<60 Hz).

X-axis and Y-axis aligned to within 0.1° (typ)

BW adjustment with a single capacitor

Single-supply operation

10,000 g shock survival

Pb Free: Compatible with Sn/Pb and Pb-free solder processes

The user selects the bandwidth of the accelerometer using

capacitors C_Xand C_Yat the X_OUTand Y_OUTpins. Bandwidths

of 0.5 Hz to 2.5 kHz can be selected to suit the application.

APPLICATIONS

Cost-sensitive motion- and tilt-sensing applications

Smart hand-held devices

The ADXL322 is available in a 4 mm × 4 mm × 1.45 mm,

16-lead, plastic LFCSP.

Mobile phones

Sports and health-related devices

PC security and PC peripherals
