ADXL320 is a low-cost, low-power, complete dual-axis accelerometer with signal conditioned voltage outputs, all on a single monolithic IC. The product measures acceleration with a full-scale ±5g, 60 Hz frequency. The ADXL320 features a small 4 mm × 4 mm × 1.45 mm LFCSP package, 2 mg resolution, wide supply voltage range of 2.4 V to 5.25 V, low power of 350 µA at VS = 2.4 V (typ), good zero g bias stability, good sensitivity accuracy, X-axis and Y-axis aligned to within 0.1° (typ), BW adjustment with a single capacitor, single-supply operation, and 10,000 g shock survival.
The ADXL320 is a low‑cost, low‑power dual‑axis accelerometer with signal‑conditioned voltage outputs, offered in a thin 4 mm × 4 mm × 1.45 mm LFCSP package. It measures acceleration over a full‑scale range of ±5 g and can detect both dynamic (vibration) and static (gravity) acceleration.
The document includes detailed specifications, absolute maximum ratings, pin descriptions, performance charts, bandwidth setting using external capacitors, self‑test procedures, tilt‑sensor operation, mechanical dimensions, and ordering information.
