DESCRIPTION
The LIS2L02AS is a dual-axis linear accelerometer
that includes a sensing element and an IC interface
able to take the information from the sensing element
and to provide an analog signal to the external world.
The sensing element, capable to detect the acceler-
ation, is manufactured using a dedicated process
called THELMA (Thick Epi-Poly Layer for Microactu-
ators and Accelerometers) developed by ST to pro-
duce inertial sensors and actuators in silicon.
The IC interface instead is manufactured using a
CMOS process that allows high level of integration to
design a dedicated circuit which is trimmed to better
match the sensing element characteristics.
The LIS2L02AS has a user selectable full scale of 2g,
6g and it is capable of measuring accelerations over

a maximum bandwidth of 4.0 KHz for both the X and
Y axis. The device bandwidth may be reduced by us-
ing external capacitances. A self-test capability al-
lows the user to check the functioning of the system.
The LIS2L02AS is available in plastic SMD package
and it is specified over a temperature range extend-
ing from -40°C to +85°C.
The LIS2L02AS belongs to a family of products suit-
able for a variety of applications:
– Antitheft systems
– Inertial navigation
– Virtual reality input devices
– Vibration Monitoring, recording and compen-
– Appliance control
– Robotics

Equivalent electrical circuit 1.2 IC Interface The complete signal processing uses a fully differential structure, while the final stage converts the differential signal into a single-ended one to be compatible with the external world. The first stage is a low-noise capacitive amplifier that implements a Correlated Double Sampling (CDS) at its output to cancel the offset and the 1/f noise. The produced signal is then sent to two different S& ...
