Description

The LY3100ALH is a high performance low-power

single-axis micromachined gyroscope capable of

measuring angular rate along yaw axis.

It provides excellent temperature stability and

high resolution over extended operating

temperature range (-40°C to +85°C).

The LY3100ALH has a full scale of ±1000 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 LY3100ALH 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.
