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.
