• SPI (3- or 4-wire) and I²C digital interfaces
• Wide temperature range: −40°C to +85°C
• 10,000 g shock survival
• Pb free/RoHS compliant
• Small and thin: 3 mm × 5 mm × 1 mm LGA package

• Concussion and head trauma detection
• High force event detection

The ADXL375 is a small, thin, 3-axis MEMS accelerometer that provides low power consumption and high resolution measurement up to ±200 g. The digital output data is formatted as 16-bit, twos complement data and is accessible through a SPI (3- or 4-wire) or I²C digital interface.

An integrated memory management system with a 32-level first in, first out (FIFO) buffer can be used to store data to minimize host processor activity and lower overall system power consumption.

Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.

The ADXL375 is supplied in a small, thin, 3 mm × 5 mm × 1 mm, 14-lead LGA.
