ADXL320EB: Small and Thin, ±5 g Accelerometer
The ADXL320 is a low cost, 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 ±5g (typical). It can also measure both dynamic acceleration (vibration) and static acceleration (gravity)
The ADXL320’s typical noise floor is 250 µg/√Hz, allowing signals below 2 mg to be resolved in tilt-sensing applications using narrow bandwidths (<60 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 ADXL320 is available in a very thin 4 mm × 4 mm × 1.45 mm, 16-lead, plastic LFCSP
Benefits:
- Two axis accelerometer in small (4mm x 4mm x 1.45mm) LFCSP package allows adding inertial sensing in
space-critical handheld devices - Low power and wide supply voltage range (2.4V to 5.25V) for battery powered applications
- Innovative circuit design provides sensitivity, zero-g bias stability over temperature - eliminates need for
external compensation
