ADXL375 Datasheet | Analog Devices

FEATURES Low power: as low as 35 µA in measurement mode and 0.1 µA in standby mode at VS = 2.5 V Power consumption scales automatically with bandwidth Embedded, 32-level FIFO buffer minimizes processor load Bandwidth of up to 1 k Hz Bandwidth selectable via serial mand Shock event 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- or 4-wire) and I2C digital interfaces Wide temperature range: - 40°C to +85°C 10,000 g shock survival Pb free/Ro HS pliant Small and thin: 3 mm × 5 mm × 1 mm LGA package APPLICATIONS Concussion and head trauma detection High force event detection 3-Axis, ±200 g Digital MEMS Accelerometer GENERAL DESCRIPTION The ADXL375 is a small, thin, 3-axis accelerometer that provides low power consumption and high resolution measurement up to ±200 g. The digital output data is formatted as 16-bit, twos plement 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.
