GENERAL DESCRIPTION
The MXR9500G/M is a low cost, tri axis accelerometer
fabricated on a standard, submicron CMOS process. It is a
complete sensing system with on-chip mixed signal
processing. The MXR9500G/M measures acceleration with
a full-scale range of ±1.5 g and a sensitivity of 500mV/g
@3.0V at 25°C. It can measure both dynamic acceleration
(e.g. vibration) and static acceleration (e.g. gravity). The
MXR9500G/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 PCB assembly and at customer field
application.

FUNCTIONAL BLOCK DIAGRAM
The MXR9500G/M provides three ratiometric analog
outputs that are set to 50% of the power supply voltage at
zero g.
The Max. noise floor is 1 mg/ Hz allowing signals
below 1 milli-g to be resolved at 1 Hz bandwidth. The
MXR9500G/M is packaged in a hermetically sealed,
surface mount LCC 16pins package (7 mm x 7 mm x 1.8
mm height) and is operational over a -40°C to +85°C (M) and
0°C to +70°C (G) temperature range.
I2C fast mode interface is soon available in the next generation
chip.
