GENERAL DESCRIPTION
The MXR6999G/M is a low noise and low profile, dual
axis accelerometer fabricated on a standard, submicron
CMOS process.
on-chip mixed mode signal processing. The MXR6999G/M
measures acceleration with a full-scale range of ±0.6 g and
a sensitivity of 1000mV/g @3V at 25°C. It can measure
both dynamic acceleration (e.g., vibration) and static
acceleration (e.g., gravity). The MXR6999G/M 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.

Low Profile, Low Power
±1.0g Dual Axis Accelerometer with
Ratiometric Outputs
The MXR6999G/M provides two ratiometric analog
outputs. The maximum noise floor is 1 mg/ Hz allowing
signals below 1mg to be resolved at 1 Hz bandwidth. The
MXR6999G/M is available in a hermetically sealed low
profile LCC surface mount package (5mm x 5mm x
1.55mm
70°C (G) temperature range.

... An accelerometer uses the force of gravity as an input to determine the inclination angle of an object. A MEMSIC accelerometer is most sensitive to changes in position, or tilt, when the accelerometer’s sensitive axis is perpendicular to the force of gravity, or parallel to the Earth’s surface. Similarly, when the accelerometer’s axis is parallel to the force of gravity (perpendicular to the Earth’ ...
