Features:
• Digital output (I2C/SPI) for processor system performance
• Low-profile 14-pin 3mm x 5mm x 0.8mm LGA package
• LGA volume is 77 percent smaller than Quad Flat No-Lead
(QFN) package
• XYZ: three axes of sensitivity in one device (2g, 4g, 8g)
• Low current consumption: 400 µA
• Standby mode: 5 µA
• Low-voltage operation: 2.4 V - 3.6 V
• Customer assigned registers for offset calibration
• Programmable threshold interrupt output
• Level detection for motion recognition (shock, vibration, freefall)
• Single or double click (pulse) recognition
• High sensitivity
— 64 LSB/g at 2g
— 64 LSB/g at 8g in 10-bit mode
