方案描述:

The MMA7660FC is a Digital Output (I2C), very low power, low profile capacitive micro machined accelerometer featuring a low pass filter, compensation for 0g offset and gain errors, and conversion to 6- bit digital values at a user configurable output data rate. The device can be used for sensor data changes, product orientation, and gesture detection through an interrupt pin (INT). The device is housed in an extremely small 3mm x 3mm x 0.9mm DFN package.
