+description: |
+ 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.
