Description
The LPR530AL is a low-power two-axis
micromachined gyroscope able to measure
angular rate along pitch and roll axes. It provides
excellent temperature stability and high resolution
over extended operating temperature range
(-40°C +85°C).
The LPR530AL has a full scale of ±300 °/s and is
capable of detecting rates with a -3 dB bandwidth
up to 140Hz. 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.
LPR530AL 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.
