Analog Devices Inc. ADXL100x MEMS 가속도계

Analog Devices ADXL100x MEMS 가속도계는 산업 환경에서의 모니터링 애플리케이션을 위한 고해상도 진동 측정 기능을 제공합니다. 이 가속도계는 ±100g(ADXL1001), ±50g(ADXL1002) 및 ±500g(ADXL1004)의 풀 스케일 범위로 제공됩니다. ADXL100x 가속도계는 확장된 주파수 범위에서 25μg/√Hz에서 125μg/√Hz까지 초저잡음 범위를 제공합니다. 이 장치는 안정적이고 반복 가능한 감도를 보여주고 최대 10,000g의 외부 충격에 대한 내성이 있습니다. ADXL100x MEMS 가속도계는 통합형 완전 정전식 ST(Self Test) 기능 및 OR(OverRange) 표시기를 포함합니다. ST 기능과 OR 표시기는 임베디드 애플리케이션에 유용한 고급 시스템 수준 기능들을 지원합니다. 저전력 3.3~5.25V 단일 전원으로 작동되는 이런 가속도계를 사용하면 무선 센서 제품도 용이하게 설계할 수 있습니다. 5mm × 5mm × 1.80mm LFCSP 패키지로 제공되는 ADXL100x MEMS 가속도계는 산업 환경의 -40~+125°C 온도 범위에서 작동합니다.

The ADXL100x MEMS Accelerometers include an integrated full electrostatic Self Test (ST) function and an OverRange (OR) indicator. The ST function and OR indicator enable advanced system level features that are useful for embedded applications. With its low-power 3.3V to 5.25V single-supply operation, the accelerometers also facilitate wireless sensing product design.

Available in a 5mm x 5mm x 1.80mm LFCSP package, the ADXL100x MEMS Accelerometers are rated for an industrial -40°C to +125°C temperature range.
