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 CX and CY at the XFILT and YFILT 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
8-terminal hermetic CLCC package

Table 1. TA = 25oC, VDD = 3 V, RBIAS = 125 kΩ, Acceleration = 0 g, unless otherwise noted.) 1 Alignment error is specified as the angle between the true and indicated axis of sensitivity (). Figure 1 Cross axis sensitivity is the algebraic sum of the alignment and the inherent sensitivity errors.
3 Defined as the output change from ambient to maximum temperature or ambient to minimum temperature.
ABSOLUTE MAXIMUM RATINGS
Table 2. Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress rat-
ing only and functional operation of the device at these or any
other conditions above those indicated in the operational sec-
tion of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
