Description
The LIS3DSH is an ultra-low-power high-
performance three-axis linear accelerometer
belonging to the “nano” family with an embedded
state machine that can be programmed to
implement autonomous applications.
The LIS3DSH has dynamically selectable full
scales of 2g/±4g/6g/8g/16g and is capable of
measuring accelerations with output data rates
from 3.125 Hz to 1.6 kHz.
The self-test capability allows the user to check
the functioning of the sensor in the final
application.
The device can be configured to generate
interrupt signals activated by user-defined motion
patterns.
The LIS3DSH has an integrated first-in, first-out
(FIFO) buffer allowing the user to store data in
order to limit intervention by the host processor.
The LIS3DSH 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.
