ST LY330ALH User Manual
LY330ALH
LGA-10 (3x5x1 mm)
MEMS motion sensor: high performance ±300 dps analog yaw-rate
gyroscope
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 LY330ALH 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.

Description
The LY330ALH is a high performance low-power
single-axis micro-machined gyroscope capable of
measuring angular rate along the yaw axis.
It provides excellent temperature stability and high
resolution over extended operating temperature
range (-40 °C to +85 °C).
The LY330ALH has a full scale of ±300 dps and is
capable of detecting rates with a -3 dB bandwidth
up to 140 Hz.
