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.
