ADXL375BCCZ-RL

ADXL375BCCZ-RL is a small, thin, 3-axis accelerometer that provides low power consumption and high-resolution measurements up to ±200g. The digital output data is formatted as 16bit, 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. It is used in applications such as concussion and head trauma detection, and high-force event detection.

• Power consumption scales automatically with bandwidth, 10,000g shock survival
• Embedded, 32-level FIFO buffer minimizes processor load
• Bandwidth selectable via serial command, shock event detection
• Activity/inactivity monitoring, supply voltage range from 2V to 3.6V
• I/O voltage range: 1.7V to VS, SPI (3- or 4-wire) and I²C digital interfaces
• Measurement range is ±200g typical at (TA = 25°C, VS = 2.5V)
• Nonlinearity is ±0.25% typical at (TA = 25°C, VS = 2.5V)
• Cross-axis sensitivity is ±2.5% typical at (TA = 25°C, VS = 2.5V)
• Supply current (measurement mode) is 145µA typical at (TA = 25°C, VS = 2.5V, VDD I/O = 2.5V)
• Operating temperature range from -40°C to +85°C, 14-terminal LGA package
