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
