The ADXL326 is a small, low power, complete 3-axis accelerometer with signal conditioned voltage outputs from Analog Devices. It measures acceleration with a minimum full-scale range of ±16 g.
The ADXL326 accelerometer provides three‑axis sensing in a 4 mm × 4 mm × 1.45 mm LFCSP package. It operates from a single 1.8 V to 3.6 V supply and consumes about 350 µA typical current. The device outputs ratiometric analog voltages proportional to acceleration and includes built‑in temperature compensation.
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 1600 Hz for X/Y and 0.5 Hz up to 550 Hz for Z. The sensor survives 10,000 g shock, offers low noise (300 µg/√Hz), and operates from –40 °C to +85 °C, making it suitable for mobile, gaming, and health‑monitoring applications.
| Measurement Range | ±16 g |
|---|---|
| Supply Voltage | 1.8 V to 3.6 V |
| Supply Current | 350 µA (typical) |
| Noise Density | 300 µg/√Hz rms |
| Operating Temperature Range | –40 °C to +85 °C |
| Shock Survival | 10,000 g |

The device operates from 1.8 V to 3.6 V.
Bandwidth is selected by adding a single capacitor to each axis (C X, C Y, C Z) on the X, Y, and Z output pins.
Typical supply current is about 350 µA.
The ADXL326 can survive up to 10,000 g shock.
