ADXL312 is a 3-axis, ±1.5 g/±3 g/±6 g/±12 g digital accelerometer with ultralow power, user-selectable resolution, embedded FIFO technology, flexible interrupt modes, and wide temperature range.
The ADXL312 is a small, thin 3‑axis accelerometer that provides high‑resolution (up to 13‑bit) measurements over selectable ranges of ±1.5, ±3, ±6 and ±12 g. It offers ultralow power consumption (as low as 57 pA in measurement mode) and supports both SPI (3‑ and 4‑wire) and I²C digital interfaces. Integrated features include a 32‑level FIFO, activity/inactivity detection, and flexible interrupt mapping.
The device operates from 2.0 V to 3.6 V, survives shocks up to 10,000 g, and is qualified for automotive applications. It is supplied in a 5 mm × 5 mm × 1.45 mm 32‑lead LFCSP package and is RoHS compliant.
