ADXL05

The ADXL05 is a complete acceleration measurement system on a single monolithic IC. The ADXL05 will measure accelerations with full-scale ranges of ±5 g to ±1 g or less. Typical noisefloor is 500 mg/ÖHz, (12´ less than the ADXL50), allowing signals below 5 milli-g to be resolved. The ADXL05 is a force balanced capacitive accelerometer with the capability to measure both ac accelerations (typical of vibration) or dc accelerations (such as inertial force or gravity). Three external capacitors and a +5 volt regulated power supply are all that is required to measure accelerations up to ±5 g. Three resistors are used to configure the output buffer amplifier to set scale factors from 200 mV/g to 1 V/g. External capacitors may be added to the resistor network to provide 1 or 2 poles of filtering. No additional active components are required to interface directly to most analog to digital converters (ADCs).

The device features a TTL compatible self-test function that can electrostatically deflect the sensor beam at any time to verify that the sensor and its electronics are functioning correctly.

The ADXL05 is available in a hermetic 10-pin TO-100 metal can, specified over the 0°C to +70°C commercial, and 40°C to +85°C industrial temperature ranges. Contact factory for availability of automotive grade devices.
