GENERAL DESCRIPTION
The MXA2500E is an ultra low noise and low cost, dual
axis accelerometer fabricated on a standard, submicron
CMOS process. It is a complete sensing system with on-
chip mixed mode signal processing. The MXA2500E
measures acceleration with a full-scale range of
±
1
g
and a
sensitivity of 500mV/g at 25
°
C. (The MEMSIC
accelerometer product line extends from
±
0.5
g
to
±
250
g
with custom versions available above
±
10
g
.) It can
measure both dynamic acceleration (e.g., vibration) and
static acceleration (e.g., gravity). The MXA2500E 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 of 50,000
g,
leading to significantly lower failure
rates and lower loss due to handling during assembly.

MXA2500E FUNCTIONAL BLOCK DIAGRAM
The MXA2500E provides an absolute analog output
The
typical noise floor is 0.2 m
g
/
Hz
allowing signals below
1 milli-
g
to be resolved at 1 Hz bandwidth.
The 3dB
rolloff of the device occurs at 17 Hz but is expandable to
>160 Hz (ref. Application Note AN-00MX-003). The
MXA2500E is available in a low profile LCC surface
mount package (5 mm x 5 mm x 2 mm). It is hermetically
sealed and is operational over a -40
°
C to +105
°
C
temperature range. It also contains an on-chip temperature
sensor and a bandgap voltage reference.
Due to the standard CMOS structure of the MXA2500E,
additional circuitry can easily be incorporated into custom
versions for high volume applications. Contact the factory
for more information.
