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 accelerations (such as inertial force, gravity or tilt).
Output scale factors from 250 mV/g to 1.
5 V/g are set using the on-board uncommitted amplifier and external resistors.
The device features an on-board temperature sensor with an output of 8 mV/°C for optional temperature compensation of offset vs.
temperature for high accuracy application.
The ADXL105 is available in a hermetic 14-lead surface mount Cerpak with versions specified for the 0°C to +70°C, and –40°C to +85°C temperature ranges.
