The ADXL311 is a low cost, low power, dual axis iMEMS® accelerometer that will measure acceleration with a full-scale range of ±2g. This complete dual axis accelerometer integrates signal conditioned voltage outputs on a single monolithic IC and 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 300ug per root Hz at 3V operation, allowing signals below 2mg (0.1° of inclination) to be resolved in tilt sensing applications using narrow bandwidths (10Hz). The ADXL311 is available in 5mm x 5mm x 2mm 8 lead hermetic LCC package.
