The DD-AM-375 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 complement data and is accessible through a SPI (3- or 4-wire) or I2C digital interface.

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


  • 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 kHz
  • Bandwidth selectable via serial command
  • 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/RoHS compliant
  • Small and thin: 3 mm × 5 mm × 1 mm LGA package


  • Concussion and head trauma detection
  • High force event detection
