GENERAL DESCRIPTION
The ADXL311 is a 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 180 million Analog Devices
accelerometers shipped to date, with demonstrated 1 FIT
reliability (1 failure per 1 billion device operating hours).
The ADXL311 measures 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.

Ultracompact ±2g Dual-Axis Accelerometer
The typical noise floor is 300 µg/√
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
of 1 Hz to 3 kHz can be selected to suit the application.
The ADXL311 is available in a 5 mm × 5 mm × 2 mm,
8-terminal, hermetic LCC package.
