Product Introduction
The ADXL382 is a low noise density, low power, 3- axis accelerometer with selectable measurement ranges. The ADXL382 supports ± 15g, ± 30g, and ± 60g ranges.
The ADXL382 offers industry leading noise, enabling precision applications with minimal calibration. The low noise and low power of the ADXL382 enables accurate measurements of audio signals or heart sounds even in high vibration environments.
The ADXL382 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 ADXL382 has many features to enable true system level performance. These features include a built-in micropower temperature sensor, single tap, double tap, or triple tap detection, and a state machine to prevent false triggering. In addition, the ADXL382 has provisions for external control of the sampling time and/or an external clock.
The ADXL382 operates on a wide, 2.25V to 3.6V supply range (or 1.8V supply) and can interface, if necessary, to a host operating on a separate supply voltage. The ADXL382 is available in a 14-terminal, 2.9mm×2.8mm×0.87mm LGA package.
