The ADXL380/ADXL382 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, and the ADXL382 supports +/-15 g, +/-30 g and +/-60 g ranges. The ADXL380/ADXL382 offers industry leading noise, enabling precision applications with minimal calibration. The low noise, and low power ADXL380/ADXL382 enables accurate measurement in an environment with high vibration, heart sounds and audio. In addition to its low power consumption, the ADXL380/ADXL382 has many features to enable true system level performance. These include a built-in micropower temperature sensor, single / double / triple tap detection and a state machine to prevent a false triggering. In addition, the ADXL380/ADXL382 has provisions for external control of the sampling time and/or an external clock.
