Description
The LIS332AR is a miniaturized low-power 3-axis linear accelerometer belonging to the “nano” family of ST motion sensors.
It includes a sensing element and an IC interface to provide an analog signal to the external world.
The sensing element, capable of detecting the acceleration, is manufactured using a dedicated process developed by ST to produce motion sensors and actuators in silicon.
The IC interface is manufactured using a CMOS process that allows the design of a dedicated

circuit which is trimmed to better match the sensing element characteristics.
The LIS332AR has a full-scale of ±2 g, and is capable of measuring accelerations over a maximum bandwidth of 2.
0 kHz.
The device bandwidth may be reduced by using external capacitors.
The self-test capability allows the user to check the functioning of the sensor in the final application.
ST is already in the field with several hundred million sensors which have received excellent acceptance from the market in terms of quality, reliability and performance.
The LIS332AR is provided in a plastic land grid array (LGA) package.
Several years ago ST successfully pioneered the use of this package for accelerometers.
Today, ST has the widest manufacturing capability and strongest expertise in the world for production of sensors in plastic LGA packages.
