GENERAL DESCRIPTION
The MXR7305VF is a low cost, dual axis accelerometer
built on a standard, submicron CMOS process. 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 roll-
off 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’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. Contact Memsic’s
local office for more information.
