STMicroelectronics IIS2DH
Ultra low-power high performance 3-axes accelerometer with digital output for industrial applications
The IIS2DH is an ultra-low-power high-performance three-axis linear accelerometer with digital I2C/SPI serial interface standard output. The IIS2DH has user-selectable full scales of ±2g/±4g/±8g/±16g and is capable of measuring accelerations with output data rates from 1 Hz to 5.3 kHz.
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 IIS2DH 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.
