Description
The LSM6DSRX is a system-in-package featuring a 3D
digital accelerometer and a 3D digital gyroscope with
an extended full-scale range for the gyroscope, up to
4000 dps, and high stability over temperature and time.
The LSM6DSRX supports main OS requirements,
offering real, virtual and batch sensors with 9 kbytes
with FIFO compression up to three times for dynamic
data batching.
ST’s family of MEMS sensor modules leverages the
robust and mature manufacturing processes already
used for the production of micromachined
accelerometers and gyroscopes.
The LSM6DSRX has a full-scale acceleration range of
±2/±4/±8/±16 g and an angular rate range of
±125/±250/±500/±1000/±2000/±4000 dps.
The LSM6DSRX embeds a broad range of advanced
functions supporting Android wearable sensors and
programmable sensors (suitable for activity
recognition).
The LSM6DSRX is available in a plastic land grid array
(LGA) package.
