GENERAL DESCRIPTION
The ADXL311 is a low cost, low power, complete dual-axis
accelerometer with signal conditioned voltage outputs, all on a
single monolithic IC. The ADXL311 is built using the same
proven iMEMS process used in over 100 million Analog
Devices accelerometers shipped to date, with demonstrated
1 FIT reliability (1 failure per 1 billion device operating hours).
The ADXL311 will measure acceleration with a full-scale
range of
±
2 g.The ADXL311 can measure both dynamic
acceleration (e.g., vibration) and static acceleration (e.g.,
gravity). The outputs are analog voltages proportional to
acceleration.
The typical noise floor is 300 μg
√
Hz
allowing signals below
2 mg(0.1° of inclination) to be resolved in tilt sensing appli-
cations using narrow bandwidths (10 Hz).
The user selects the bandwidth of the accelerometer using
capacitors C

pins. Bandwidths
of 1 Hz to 2 kHz may be selected to suit the application.
The ADXL311 is available in a 5 mm × 5 mm × 2 mm
