LYPR540AH： MEMS motion sensor： 3 axis analog output gyroscope

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.

ST 3 axis gyroscope family leverages on robust and mature manufacturing process already used for the production of hundreds million 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.
