It is a complete sensing system with on-chip mixed mode signal processing. The MXR2999E measures acceleration with a full-scale range of ±0.5 g and a sensitivity of 1000mV/g @5Vat 25°C. It can measure both dynamic acceleration (e.g., vibration) and static acceleration (e.g., gravity). The MXR2999E 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 up to 50,000 g, leading to significantly lower failure rates and lower loss due to handling during assembly.

No license is granted by implication or otherwise under any patent or patent rights of MEMSIC. MEMSIC MXR2999E Rev.G Sck (optional) Page 1 of 8 The MXR2999E provides two ratiometric analog outputs. The typical noise floor is 0.2 mg/ Hz allowing signals below 1mg to be resolved at 1 Hz bandwidth. The 3dB rolloff of the device occurs at 17 Hz. The offset drift over temperature is ±0.4mg/°C. The MXR2999E is available in a small surface mount package (5mm x 5mm x 2mm). 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 MXR2999E, additional circuitry can easily be incorporated into custom versions for high volume applications.
