Description

The LIS3DH has dynamically 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 self-test capability

allows the user to check the functioning of the

sensor in the final application. The device may be

configured to generate interrupt signals using two

independent inertial wake-up/free-fall events as

well as by the position of the device itself.

Thresholds and timing of interrupt generators are

programmable by the end user on the fly. The

LIS3DH has an integrated 32-level first-in, firstout

(FIFO) buffer allowing the user to store data in

order to limit intervention by the host processor.

The LIS3DH is available in small thin plastic land

grid array package (LGA) and is guaranteed to

operate over an extended temperature range

from -40 °C to +85 °C.
