It is a complete sensing system with onchip mixed mode signal processing. The MXA2500E measures acceleration with a full-scale range of ±1 g 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 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 typical noise floor is 0.2 mg/ Hz allowing signals below 1 mg 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 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.
