The MMA7660FC is a ±1.5 g 3-Axis Accelerometer with Digital Output (I2C). It is a very low
power, low profile capacitive MEMS sensor featuring a low pass fi
lter, compensati
onfor 0g offset and gain errors, and conversion to 6-bit digital values at a user configurable samples
persecond. The device can be used for sensor data changes, product orientation, and gesture detection through an interrupt
pin(INT). The device is housed in a small 3mm x 3mm x 0.9mm DFN package.
MMA7660FC主要特性:
• Digital Output (I2C)
• 3mm x 3mm x 0.9mm DFN Package
• Low Power Current Consumption: Off Mode: 0.4 &
mu;A, Standby Mode: 2 μA, Active Mode: 47 μA at 1 ODR
• Configurable Samples per Second from 1 to 120 samples a second.
• Low Voltage Operation:
– Analog Voltage: 2.4 V - 3.6 V
– Digital Voltage: 1.71 V - 3.6 V
• Auto-Wake/Sleep Feature for Low Power Consumption
• Tilt Orientation Detection for Portrait/Landscape Capability
• Gesture Detection Including Shake Detection and Tap Detection
• Ro
bust Design, High Shocks Survivability (
10,000 g)
