AIS328DQ中文资料汽车3轴加速度计，超低功耗，SPI/I2C数字输出，AEC-Q100认证数据手册ST规格书

描述 Description

The AIS328DQ is an ultra-low-power high-performance 3-axis linear accelerometer with a digital serial interface SPI standard output. An I²C compatible interface is also available. The device features ultra-low-power operational modes that allow advanced power saving and smart sleep-to-wakeup functions. The AIS328DQ has dynamic user-selectable full scales of ±2g/±4g/±8g and is capable of measuring accelerations with output data rates from 0.5 Hz to 1 kHz. The self-test capability allows the user to check the functioning of the sensor in the final application. The device may be configured to generate an interrupt signal through inertial wakeup events, or by the position of the device itself. Thresholds and the timing of interrupt generators are programmable by the end user on-the-fly. Available in a small quad flat pack no-lead package (QFPN) with a 4x4 mm footprint, the AIS328DQ is able to respond to the trend towards application miniaturization and is guaranteed to operate over a temperature range from -40 °C to +105 °C.
