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是一三轴数字输出的加速度计，其中包括一个传感元件和一个集成电路接口能够从传感元件的信息，通过SPI串行接口，外部世界提供实测加速度信号。我²C兼容接口也可。

的传感元件，能够检测的加速度，使用一个专门的过程开发的由圣生产的惯性传感器和致动器在硅中使用。

IC接口而不是使用CMOS工艺，使高集成度设计一个专门的电路，工厂调整以更好地匹配传感元件特性制造。

ais326dq有一个全面的用户选择的±2 g，±6 g，它是能够测量加速度超过所有轴的带宽为640 Hz。该设备的带宽可根据应用要求选择。自检功能允许用户检查系统的功能。
