L3G462A
MEMS motion sensor:
± 625 dps full scale - 3-axis analog gyroscope
Preliminary data
Features
± 625 dps full scale
Wide supply voltage range 2.4 V to 3.6 V
Embedded power-down and sleep mode to
save power consumption and shorten turn-on
time
Integrated temperature sensor
Embedded low pass filter
High shock survivability
Extended operating temperature range (-40 °C
to 85 °C)
ECOPACK® RoHS and “Green” compliant
Applications
Gaming and virtual reality input devices
Motion control with MMI (man-machine
interface)
GPS navigation systems
Appliances and robotics
LGA-16 (4x4x1.1 mm)
The IC interface is manufactured using a CMOS
process that allows a high level of integration to
design a dedicated circuit which is trimmed to
better match the sensing element characteristics.
The L3G462A is available in a plastic land grid
array (LGA) package and can operate within a
temperature range from -40 °C to +85 °C.
Description
The L3G462A is a low-power 3-axis angular rate
sensor.
It includes a sensing element and an IC interface
able to provide the measured angular rate to the
external world through three analog outputs.
The sensing element is manufactured using a
dedicated micromachining process developed by
ST to produce inertial sensors and actuators on
silicon wafers.
