The MXD7210ML 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 MXD7210ML measures acceleration with a full-scale range of 10
g and a sensitivity of 4%/g @5V. It can measure both dynamic acceleration (e.g.
vibration) and static acceleration (e.g. gravity).
The MXD7210ML 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 MXD7210ML 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 0.4 mg/ allowing signals
below 1milli-g to be resolved at 1 Hz bandwidth. The MXR7210ML 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
