Technical Data
±1.5g, ±6g Three Axis Low-g
Micromachined Accelerometer
The MMA7361L 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
MMA7361L includes a Sleep Mode that makes it ideal for handheld battery
powered electronics.
