The ADXL380 is a low noise density, low power, 3-axis accelerometer with selectable measurement ranges. The ADXL380 supports the ±4 g, ±8 g, and ±16 g ranges.
The ADXL380 offers industry leading noise, enabling precision applications with minimal calibration. The low noise and low power ADXL380 enables accurate measurements of audio signals or heart sounds even in high vibration environments.
The ADXL380 multifunction pin names may be referenced only by their relevant function for either the serial peripheral interface (SPI) or inter-IC(I2C) interface, or these pin names can be referenced by their audio function (pulse density modulation (PDM), inter-IC sound (I2S), or time division multiplexing (TDM)).
In addition to its low power consumption, the ADXL380 has many features to enable true system level performance. These features include a built-in micropower temperature sensor, singletap, double tap, and triple tap detection, and a state machine to prevent false triggering. In addition, the ADXL380 has provisions for external control of the sampling time and/or an external clock.
The ADXL380 operates on a wide, 2.25 V to 3.6 V supply range (or 1.8 V supply) and can interface, if necessary, to a host operating on a separate supply voltage. The ADXL380 is available in a 14-terminal, 2.9 mm × 2.8 mm × 0.87 mm, LGA package.
