Applications

Description

The LPY530AL is a low-power two-axis

micromachined gyroscope able to measure

angular rate along pitch and yaw axes.

It provides excellent temperature stability and

high resolution over extended operating

temperature range (-40°C to +85°C).

The LPY530AL has a full scale of ±300 °/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 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.

LPY530AL 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.
