MODEL 3255A ACCELEROMETERSPECIFICATIONSPC Board Mountable Accelerometer
Amplified Output
Temperature CompensatedHigh Over-Range Protection

The Model 3255A is a signal conditioned board mountable
MEMS accelerometer available in ±25g to ±500g ranges.
The package can be mounted in one of two orientations,allowing the measurement axis to be either parallel orperpendicular to the mounting surface without the use ofcostly brackets. The accelerometer incorporates integral
temperature compensation and offers a flat frequency
response from DC to 1500Hz.
