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
25
°
C
. It can measure both dynamic acceleration (e.g.
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.

MXR7210G/M FUNCTIONAL BLOCK DIAGRAM
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 m
g
/
below 1milli-
g
to be resolved at 1 Hz bandwidth.
The
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
0
