The ADXL105 offers significantly increased bandwidth and reduced noise versus previously available micromachined devices. The ADXL105 measures acceleration with a full-scale range up to ± 5 g and produces an analog voltage output. Typical noise floor is 225 µg√Hz allowing signals below 2 m g to be resolved. A 10 kHz wide frequency response enables vibration measurement applications. The product exhibits significant reduction in offset and sensitivity drift over temperature compared to the ADXL05. The ADXL105 can measure both dynamic accelerations, (typical of vibration) or static a...
