2g ACCELERATION SENSOR
Notice:This is not a final specification.
Some parametric limits are subject to change.
DESCRIPTION
MAS1390P is a
2g acceleration sensor .
The sensor element and the signal processing circuit
are integrated in one package, it is small and it can
be mounted directly on a printed board, so it helps
reduce the overall size of the systems.
FEATURES
Capacitive type acceleration sensor
Output ratiometric to supply
16-pin plastic SOP
Wide operation temperature range, small size
and lightweight.
APPLICATION
Car Navigation
Projectors
Virtual Reality Input Devices
Inclination Meter
Vibration Measurement
Velocity and Position Measurement
