The
MMA7331L is a low power, low profile capacitive micromachined
accelerometer featuring signal conditioning, a 1-pole low pass filter,
temperature compensation, self test, 0g-detect which detects linear
freefall, and g-Select which allows for the selection between 2
sensitivities. Zero-g offset and sensitivity are factory set and
require no external devices. The MMA7331L includes a sleep mode that
makes it ideal for handheld battery powered products.
