The ADXL383 is a low noise density, low power, 3-axis accelerometer with selectable measurement ranges. The ADXL383 supports ±15 g, ±30 g, and ±60 g ranges.
The ADXL383 offers industry leading noise, enabling precision applications with minimal calibration. The low noise and low power of the ADXL383 enables accurate measurements of audio signals or heart sounds even in high vibration environments.
The ADXL383 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 ADXL383 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 ADXL383 has provisions for external control of the sampling time and/or an external clock.
The ADXL383 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 ADXL383 is available in a 14-terminal, 2.90 mm × 2.80 mm × 0.87 mm, LGA package.
