GENERAL DESCRIPTION
The MXR6999G/M is a low noise and low profile, dual
axis accelerometer fabricated on a standard, submicron
CMOS process. It is a complete sensing system with
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.
