Micromachined Accelerometer
accelerometer featuring signal conditioning, a 1-pole low pass filter,
temperature compensation, self test, and g-Select which allows for the
selection between two sensitivities. Zero-g offset and sensitivity are factory
set and require no external devices. The MMA7341LC includes a Sleep Mode
that makes it ideal for handheld battery powered electronics.
