It measures acceleration with a full-scale range of ±5g and a sensitivity of 250mV/g. The MXR7305VF provides a g-proportional ratiometric analog output above/below the zero-g point at 50% of the supply voltage. (Ref. other MEMSIC data sheets for absolute analog or digital outputs). The typical noise floor is 0.6mg / Hz , allowing signals below 1mg to be resolved at 1Hz bandwidth. The 3dB rolloff of the device occurs at 27Hz. The MXR7305V is available in a low profile LCC surface mount package (5mm x 5mm 2mm). It is hermetically sealed and operational over a -40°C to +95°C temperature range.

MEMSIC MXR7305V Rev.A Page 1 of 6 Memsic’s accelerometer technology allows for designs from ±1 g to ±70 g with custom versions available above ±70 g. It can measure both dynamic acceleration (e.g., vibration) and static acceleration (e.g., gravity). The design is based on heat convection and requires no solid proof mass. This eliminates stiction and particle problems associated with competitive devices and provide shock survival greater than 50,000 g, leading to significantly lower failure rates and lower loss due to handling during assembly and at customer field application. Due to the standard CMOS structure of the MXR7305V, additional circuitry can easily be incorporated into custom versions for high volume applications.
