Description
The LPY5150AL is a low-power dual-axis
micromachined gyroscope capable of measuring
angular rate along pitch and yaw axes.
It provides excellent temperature stability and
high resolution over an extended operating
temperature range (-40 °C to +85 °C).

The LPY5150AL has a full scale of ±1500 °/s and
is capable of detecting rates with a -3 dB
bandwidth up to 140 Hz.
The gyroscope is the combination of one actuator
and one accelerometer integrated in a single
micromachined structure.
It includes a sensing element composed by single
driving mass, kept in continuous oscillating
movement and able to react when an angular rate
is applied based on the Coriolis principle.
A CMOS IC provides the measured angular rate
to the external world through an analog output
voltage, allowing high level of integration and
production trimming to better match sensing
element characteristics.
ST’s gyroscope family leverages on robust and
mature manufacturing process already used for
the production of micromachined accelerometers.
ST is already in the field with several hundreds
million sensors with excellent acceptance from
the market in terms of quality, reliability and
performance.
LPY5150AL is provided in plastic land grid array
(LGA) package. Several years ago ST pioneered
successfully the usage of this package for
accelerometers. Today ST has the widest
manufacturing capability and strongest expertise
in the world for production of sensor in plastic
LGA package.
