DESCRIPTION

The LIS2L01 is a dual channel accelerometer that in-

cludes a sensor elements and an IC interface able to

take the information from the sensor and to provide

an analog signal to the external world.

The sensor element, capable to detect the accelera-

tion, is manufactured using a dedicated process

called ThELMA (Thick Epi-Poly layer for Microactua-

tors and Accelerometers) developed by ST to pro-

duce inertial sensor and actuator in silicon.

The IC interface instead is manufactured using a

CMOS process that allow high level of integration to

design a dedicated circuit which is trimmed to better

match the sensor element characteristics.

The LIS2L01 is capable of measuring acceleration in

the range of ±1g with a bandwidth of 30Hz, set by a

the system providing to the user a signal on a dedi-

cated pin.

The LIS2L01 is available in plastic SMD package and

it is specified over a temperature range from 0°C to

+80°C.

The LIS2L01 is a part of family products suitable for

a variety of applications:

– Virtual reality input devices

– Computer hard disk drive protection

– Computer mouse and joysticks

– Vibration Monitoring, recording and compen-

sation

– Appliance control

– Robotics
