GENERAL DESCRIPTION
The MXA6500G/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 MXA6500G/M measures acceleration with
a full-scale range of ±1 g and a sensitivity of 500mV/g @3V
at 25
vibration) and static acceleration (e.g. gravity). The
MXA6500G/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 max noise floor is 1 mg/ Hz allowing signals below
1mg to be resolved at 1 Hz bandwidth. The MXA6500G/M
is packaged in a hermetically sealed LCC surface mount
package (5 mm x 5 mm x 1.55 mm height)
It is operational over a -40
