Description
The LPY4150AL 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 LPY4150AL has a full scale of ±1500 dps
and is capable of detecting rates with a -3 dB
bandwidth up to 140 Hz.
The device includes a sensing element composed
of a single driving mass, kept in continuous
oscillation and capable of reacting, based on the
Coriolis principle, when an angular rate is applied.
A CMOS IC provides the measured angular rate
to the external world through an analog output
voltage, allowing high levels of integration and
production trimming to better match sensing
element characteristics.
ST's family of gyroscopes leverages on the
mature and robust manufacturing process already
used for the production of micro-machined
accelerometers.
ST is already in the field with several hundred
million sensors which have received excellent
acceptance from the market in terms of quality,
reliability and performance.
The LPY4150AL is available in a plastic land grid
array (LGA) package, which ST successfully
pioneered for accelerometers.Today ST has the
widest manufacturing capability and strongest
expertise in the world for production of sensors in
plastic LGA packages.
