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 +/- 1g and a sensitivity of 500mV/g at
25°C. (The MEMSIC accelerometer product line extends from +/- 0.5g to +/- 250g
with custom versions available above +/- 10g.) 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.
The MXA2500E provides an absolute analog output . The typical noise floor is 0.2
mg / 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
Due to the standard CMOS structure of the MXA2500E, additional circuitry can
easily be incorporated into custom versions for high volume applications.
