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.
