Applications

Description

The LPY510AL 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 LPY510AL has a full scale of ±100 °/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 continuos 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.

LPY510AL 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.
