iMEMS加速计

1990 年初,Analog Devices, Inc.（简称 ADI）凭借其 iMEMS®（集成微电子机械系统）惯性传感器技术革新了汽车安全气囊系统。我们作为业界认同的基于微电子机械系统（MEMS）惯性传感器市场领先供应商，到 2002 年 9 月我们已经生产了一亿多只惯性传感器。我们独特的 iMEMS 工艺能使传感器单元和信号调理电路集成在一颗芯片上，从而允许我们减小尺寸、降低功耗和节省成本，同时提高性能和定制生产能力。

鉴于我们的产品建立在非凡的产品质量和可靠性基础上，现在已有 1 亿 5 千万只传感器安装在安全至关重要的汽车安全气囊系统，并且作为衡量其它 MEMS 传感器供应商产品的检测标准。Accelerometers Part# Results: 12 # of Axes Range Sensitivity Sensitivity Accuracy (%) Output Type Typical Bandwidth (kHz) Noise Density (µg/rtHz) Voltage Supply (V) Supply Current Temp Range (°C) Package 数据手册 DataSheet 下载 ADXL322 2 +/- 2g 420 mV/g ±10 Analog2.5 2202.4 to 6
