Description
www.DataSheet4U.com
The LYPR540AH is a three axis yaw, pitch and roll
analog gyroscope featuring three separate analog
output channels.
LYPR540AH provides amplified (±400 dps full
scale) and not amplified (±1600 dps full scale)
outputs for each sensible axis available at the
same time through dedicated pins, and is capable
of detecting rates with a -3 dB bandwidth up to
140 Hz.

LGA-28L (4.4x7.5x1.1 mm)
ST 3 axis gyroscope family leverages on robust
and mature manufacturing process already used
for the production of hundreds milion
micromachined accelerometers with excellent
acceptance from the market.
Sensing element is manufactured using
specialized micromachining processes, while the
IC interfaces are realized using a CMOS
technology that allows to design a dedicated
circuit which is trimmed to better match the
sensing element characteristics.
The LYPR540AH is available 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 sensors in plastic
LGA package.
