Part Details
- Small and thin
4 mm × 4 mm × 1.45 mm LFCSP package - 3 mg resolution at 50 Hz
- Wide supply voltage range: 2.4 V to 6 V
- Low power:
350 µA at Vs = 2.4 V (typ) - Good zero g bias stability
- Good sensitivity accuracy
- 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
- Compatible with Sn/Pb and Pb-free solder processes
The ADXL321 is a small and thin, low power, complete dual-axis accelerometer with signal conditioned voltage outputs, which is all on a single monolithic IC. The product measures acceleration with a full-scale range of ±18g (typical). It can also measure both dynamic acceleration (vibration) and static acceleration (gravity).
The ADXL321’s typical noise floor is 320 µg/√Hz, allowing signals below 3 mg to be resolved in tilt-sensing applications using narrow bandwidths (<50 Hz).
The user selects the bandwidth of the accelerometer using capacitors CX and CY at the XOUT and YOUT pins. Bandwidths of 0.5 Hz to 2.5 kHz may be selected to suit the application.
The ADXL321 is available in a very thin 4 mm × 4 mm × 1.45 mm, 16-lead, plastic LFCSP.
APPLICATIONS
- Vibration monitoring and compensation
- Abuse event detection
- Sports equipment
