GENERAL DESCRIPTION
Ultralow power: as low as 23 A in measurement mode and 0.1 A in standby mode at VS = 2.5 V (typical)
Power consumption scales automatically with bandwidth User-selectable resolution
Fixed 10-bit resolution 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) Embedded memory management system with FIFO technology minimizes host processor load Single tap, double tap detection Activity, inactivity monitoring Free-fall detection Supply voltage range: 2.0 V to 3.6 V I, O voltage range: 1.7 V to VS SPI (3- and 4-wire) and I2C digital interfaces Flexible interrupt modes mappable to either interrupt pin Measurement ranges selectable via serial command Bandwidth selectable via serial command Wide temperature range ( 40°C to +85°C) 10,000 g shock survival Pb free, RoHS compliant Small and thin: 3 mm .
