The MXR7202ML is a low cost, dual axis accelerometer fabricated on a standard,
submicron CMOS process. It is a complete sensing system with on-chip mixed
The MXR7202ML measures acceleration with a full-scale range of 2
g and a sensitivity of 312mV/g @5V. It can measure both dynamic acceleration
(e.g. vibration) and static acceleration (e.g. gravity).
The MXR7202ML 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.
The MXR7202ML provides two ratiometric analog outputs that are proportional to
50% of the supply at zero g acceleration.
The typical noise floor is 0.3 mg/ allowing signals below 1
milli-g to be resolved at 1 Hz bandwidth. The MXR7202ML is packaged in a
hermetically sealed LCC surface mount package (5 mm x 5 mm x 2 mm height) and is
operational over a -40°C to +85°C (ML) temperature range. Click here
