GENERAL DESCRIPTION

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.
