GENERAL DESCRIPTION
The MXD7202GL/HL/ML/NL is a low cost, dual axis
accelerometer fabricated on a standard, submicron CMOS
process. It is a complete sensing system with on-chip mixed
signal processing. The MXD7202GL/HL/ML/NL measures
acceleration with a full-scale range of
±
2
g
and a sensitivity
of 12.5%/g @5V. It can measure both dynamic acceleration
(e.g. vibration) and static acceleration (e.g. gravity). The
MXD7202GL/HL/ML/NL 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 greater than
50,000
g,
leading to significantly lower failure rate and lower
loss due to handling during assembly and at customer field
application.

MXD7202GL/HL/ML/NL FUNCTIONAL BLOCK DIAGRAM
The MXD7202GL/HL/ML/NL provides two digital outputs
that are set to 50% duty cycle at zero g acceleration. The
outputs are digital with duty cycles (ratio of pulse width to
period) that are proportional to acceleration. The duty cycle
outputs can be directly interfaced to a microprocessor.
The typical noise floor is 0.3 m

/
below 1 milli-
g
to be resolved at 1 Hz bandwidth.
The
MXD7202GL/HL/ML/NL is packaged in a hermetically
sealed LCC surface mount package (5 mm x 5 mm x 2 mm
height) and is operational over a
