GENERAL DESCRIPTION  
The MXA2500G/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 mode signal  
processing. The MXA2500G/M measures acceleration  
with a full-scale range of ±1.7g and a sensitivity of  
500mV/g @5V at 25°C. It can measure both dynamic  
acceleration (e.g. vibration) and static acceleration (e.g.  
gravity). The MXA2500G/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 of 50,000  
g, leading to significantly lower failure rate and lower loss  
due to handling during assembly.  
The MXA2500G/M provides two absolute analog outputs.  
The typical noise floor is 0.2 mg/ 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 (reference Application Note AN-00MX-003).  
The MXA2500G/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 -40°C to 105°C(M) and 0°C to  
70°C(G) temperature range.
