The LIS2DH12 is an ultra-low-power high-performance three-axis linear accelerometer belonging to the “femto” family with digital I²C/SPI serial interface standard output.

The LIS2DH12 has user-selectable full scales of ±2g/±4g/±8g/±16g and it is capable of measuring accelerations with output data rates from 1 Hz to 5.3 kHz.

The self-test capability allows the user to check the functionality of the sensor in the final application.

The device may be configured to generate interrupt signals by two independent inertial wake-up/free-fall events as well as by the position of the device itself.

The LIS2DH12 is available in a small thin plastic land grid array package (LGA) and is guaranteed to operate over an extended temperature range from -40 °C to +85 °C.

lis2dh12是一個(gè)超低功耗高性能的三軸加速度計(jì)屬于“飛秒”家庭數(shù)字I2C/SPI串行接口標(biāo)準(zhǔn)輸出。

lis2dh12具有用戶可選的全尺度的±2g／±4G /±8g /±16G，它能夠測(cè)量加速度的輸出數(shù)據(jù)率從1赫茲到5.3千赫。

自檢功能允許用戶在最后的應(yīng)用程序中檢查傳感器的功能。

該設(shè)備可以配置為產(chǎn)生中斷信號(hào)由2個(gè)獨(dú)立的慣性喚醒/自由墜落事件，以及由該設(shè)備本身的位置。

在一個(gè)小的lis2dh12薄塑料柵格陣列（LGA）封裝提供并保證工作在擴(kuò)展溫度范圍從- 40°C + 85°C.
