±1.5g - 6g Three Axis Low-g
Micromachined Accelerometer
The MMA7260QT low cost capacitive micromachined accelerometer
features signal conditioning, a 1-pole low pass filter, temperature
compensation and g-Select which allows for the selection among 4
sensitivities. Zero-g offset full scale span and filter cut-off are factory set and
require no external devices. Includes a Sleep Mode that makes it ideal for
handheld battery powered electronics.
