The ADXL337 is a small, low-power, 3-axis accelerometer with features such as 3-axis sensing, low power consumption, and small size.
The ADXL337 accelerometer from Analog Devices provides three‑axis acceleration measurement in a compact 3 mm × 3 mm × 1.45 mm LFCSP package. It operates from a single supply of 1.8 V to 3.6 V and consumes about 300 µA typical current. The device outputs analog voltages proportional to acceleration and includes built‑in signal conditioning.
Bandwidth for each axis is set with a single external capacitor (C_X, C_Y, C_Z), allowing ranges from 0.5 Hz up to 1.6 kHz (X/Y) or 550 Hz (Z). The sensor tolerates up to 10,000 g shock and works from –40 °C to +85 °C, making it suitable for motion, tilt, shock and vibration detection in mobile, gaming, and health‑monitoring applications.
| Measurement Range | ±3 g |
|---|---|
| Sensitivity (typical) | 270 mV/g – 330 mV/g |
| Supply Current (typical) | 300 µA |
| Bandwidth (X/Y) | up to 1.6 kHz (no external filter) |
| Bandwidth (Z) | up to 550 Hz (no external filter) |
| Temperature Range (operating) | –40 °C to +85 °C |
| Shock Survival | 10,000 g |
The ADXL337 measures acceleration over a full‑scale range of ±3 g.
Bandwidth is set by adding a single external capacitor to each axis (C_X, C_Y, C_Z).
Typical supply current is about 300 µA at 3 V.
