LIS2HH12 MEMS digital output motion sensor: ultra-low-power high-performance 3-axispic accelerometer Datasheet - production data Description The LIS2HH12 is an ultra-low-power high- performance three-axis linear accelerometer belonging to the pico family. The LIS2HH12 has full scales of 2g/4g/8g and is capable of measuring accelerations with output LGA-12 (2.0x2.0x1.0 mm) data rates from 10 Hz to 800 Hz. The self-test capability allows the user to check the functioning of the sensor in the final Features application. Wide supply voltage, 1.71 V to 3.6 V The LIS2HH12 has an integrated first-in, first-out Independent IOs supply (1.8 V) and supply (FIFO) buffer allowing the user to store data in voltage compatible order to limit intervention by the host processor. Ultra-low power consumption The LIS2HH12 is available in a small thin plastic 2g/4g/8g full-scale land grid array package (LGA) and it is 2 guaranteed to operate over an extended I C/SPI digital output interface temperature range from -40 C to +85 C 16-bit data output Embedded temperature sensor Table 1.
