GENERAL DESCRIPTION
The MXR7210G/M is a low cost, dual axis accelerometer
fabricated on a standard, submicron CMOS process. It is a
complete sensing system with on-chip mixed signal
processing. The MXR7210G/M measures acceleration with
a full-scale range of ±10 g and a sensitivity of 100mV/g
@5V at
vibration) and static acceleration (e.g. gravity). The
MXR7210G/M design is based on heat convection and
requires no solid proof mass. This eliminates stiction and
particle problems associated with competitive devices and
provides shock survival greater than 50,000 g, leading to
significantly lower failure rate and lower loss due to handling
during assembly and at customer field application.

The MXR7210G/M provides two ratiometric analog outputs
that are proportional to 50% of the supply at zero g
acceleration.
The typical noise floor is 0.4 mg/ Hz allowing signals
below 1mg to be resolved at 1 Hz bandwidth.
MXR7210G/M is packaged in a hermetically sealed LCC
surface mount package (5 mm x 5 mm x 2 mm height) and is
operational over a
temperature range.

... An accelerometer uses the force of gravity as an input to determine the inclination angle of an object. A MEMSIC accelerometer is most sensitive to changes in position, or tilt, when the accelerometer’s sensitive axis is perpendicular to the force of gravity, or parallel to the Earth’s surface. Similarly, when the accelerometer’s axis is parallel to the force of gravity (perpendicular to the Earth’ ...
