IIS2DH Ultra-low-power high-performance 3-axis accelerometer with digital output for industrial applications Datasheet - production data Description The IIS2DH is an ultra-low-power high- performance three-axis linear accelerometer with 2 digital I C/SPI serial interface standard output. LGA-12 (2.0x2.0x1 mm) 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 Features 5.3 kHz. Wide supply voltage, 1.71 V to 3.6 V The device may be configured to generate interrupt signals by two independent inertial Independent IOs supply (1.8 V) and supply wake-up/free-fall events as well as by the position voltage compatible of the device itself. Ultra-low power consumption down to 2 A The self-test capability allows the user to check 2g/4g/8g/16g selectable full scales the functionality of the sensor in the final 2 I C/SPI digital output interface application. 3 operating modes: low-power, normal, high- The IIS2DH is available in a small thin plastic land resolution mode grid array package (LGA) and is guaranteed to 2 independent programmable interrupt operate over an extended temperature range generators for free-fall and motion detection from -40 C to +85 C. 6D/4D orientation detection Table 1.
