FULL RESOLUTION: where resolution increases with g range, up to 13-bit resolution at 16 g (maintaining 4 mg/LSB scale factor in all g ranges) MULTIPLE SENSING DETECT: Activity and inactivity sensing detect the presence or lack of motion by comparing the acceleration on any axis with user-set thresholds. Tap sensing detects single and double taps in any direction. Free fall sensing detects if the device is falling. COMMUNICATION: It uses both I2C and SPI (supports 3-, 4-wire SPI) interface. WIDELY APPLICATIONS: Handsets, instrumentation, Gaming and pointing devices, Industrial instrumentation, Personal navigation devices, Hard disk drive (HDD) protection, Portable gaming. ULTRA LOW POWER: as low as 23 A in measurement mode and 0.1 A in standby mode at VS = 2.5 V (typical).
