Enhanced Product 3-Axis, ±2 g/±4 g/±8 g/±16 g Digital Accelerometer Features GENERAL DESCRIPTION Ultralow power: as low as 23 µA in measurement mode and 0.1 µA in standby mode at VS = 2.5 V (typical) Power consumption scales automatically with bandwidth User-selectable resolution from 10 to 13 bits 4 mg/LSB scale factor in all g ranges 32-sample FIFO minimizes host processor load Single tap, double tap, and free-fall detection Activity/inactivity monitoring 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 mand Bandwidth selectable via serial mand 10,000 g shock survival Pb free/Ro HS pliant Small and thin: 3 mm × 5 mm × 1 mm LGA package ENHANCED PRODUCT Features Supports defense and aerospace applications (AQEC standard) Extended industrial temperature range (- 55°C to +105°C) Controlled manufacturing baseline One assembly/test site One fabrication site Enhanced product change notification Qualification data available on request APPLICATIONS Industrial equipment Aerospace equipment The ADXL345-EP is an extended performance version of the ADXL345, which is a small, thin, ultralow power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. Digital output data is formatted as 16-bit twos plement and is accessible through either a SPI (3- or 4-wire) or I2C digital interface. The ADXL345-EP is well suited for extended temperature range industrial and aerospace equipment. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (3.9 mg/LSB) enables measurement of inclination changes less than 1.0°. Several special sensing functions are provided. Activity and inactivity sensing detect the presence or lack of motion by paring the acceleration on any axis...
