+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.
