MXD2020E

The MXD2020E/F is an ultra low noise and low cost, dual axis accelerometer built on a standard, submicron CMOS process.  The MXD2020E/F measures acceleration with a full-scale range of ± 1 g. (The MEMSIC accelerometer  product line extends from ±1 g to ±200 g with custom  versions available above ±10 g.) It can measure both  dynamic acceleration (e.g., vibration) and static  acceleration (e.g., gravity).  The MXD2020E/F 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 losses due to handling during assembly.  The MXD2020E/F provides a digital output.  The outputs  are digital signals with duty cycles (ratio of pulse width to  period) that are proportional to acceleration.  The duty  cycles outputs can be directly interfaced to a micro-processor. 

The typical noise floor is 0.2mg /  allowing signals  below 1 milli-g to be resolved at 1 Hz bandwidth.  The MXD2020E/F is available in a low profile LCC surface  mount package (5mm x 5mm x 2mm height). It is  hermetically sealed and operational over a -40 to +105 temperature range.

Due to the standard CMOS structure of the MXD2020E/F, additional circuitry can easily be incorporated into custom  versions for high volume applications.  Contact the factory for more information.
