Low Noise, Low Drift, Low Power 3-Axis MEMS Accelerometer

The digital output ADXL3591 is a low noise density, low 0 g offset drift, low power, 3-axis microelectromechanical system (MEMS) accelerometer with selectable measurement ranges. The ADXL359 supports the ±10 g, ±20 g, and ±40 g ranges.

The ADXL359 offers industry leading noise, minimal offset drift over temperature, and long-term stability, enabling precision applications with minimal calibration.

The low drift, low noise, and low power ADXL359 enables accurate tilt measurement in an environment with high vibration, such as airborne inertial measurement units (IMUs). The low noise over higher frequencies is ideal for wireless condition monitoring.

The ADXL359 multifunction pin names may be referenced only by their relevant function for either the serial peripheral interface (SPI) or limited I2C interface.
