The AIS326DQ is a three axes digital output accelerometer that includes a sensing element and an IC interface able to take the information from the sensing element and to provide the measured acceleration signals to the external world through an SPI serial interface. I2C compatible interface is also available.

The sensing element, capable of detecting the acceleration, is manufactured using a dedicated process developed by ST to produce inertial sensors and actuators in silicon.

The IC interface instead is manufactured using a CMOS process that allows high level of integration to design a dedicated circuit which is factory trimmed to better match the sensing element characteristics.

The AIS326DQ has a user selectable full scale of ±2 g, ±6 g and it is capable of measuring acceleration over a bandwidth of 640 Hz for all axes. The device bandwidth may be selected accordingly to the application requirements. The self-test capability allows the user to check the functioning of the system.

The device is available in plastic quad flat package no lead surface mount (QFPN) and it is specified over a temperature range extending from -40 °C to +105 °C.

ais326dq是一三軸數(shù)字輸出的加速度計，其中包括一個傳感元件和一個集成電路接口能夠從傳感元件的信息，通過SPI串行接口，外部世界提供實測加速度信號。我2C兼容接口也可。

的傳感元件，能夠檢測的加速度，使用一個專門的過程開發(fā)的由圣生產(chǎn)的慣性傳感器和致動器在硅中使用。

IC接口而不是使用CMOS工藝，使高集成度設計一個專門的電路，工廠調(diào)整以更好地匹配傳感元件特性制造。

ais326dq有一個全面的用戶選擇的±2 g，±6 g，它是能夠測量加速度超過所有軸的帶寬為640 Hz。該設備的帶寬可根據(jù)應用要求選擇。自檢功能允許用戶檢查系統(tǒng)的功能。
