Analog Devices ADXL372 - Micropower, 3-Axis, ±200 g Digital Output, MEMS

Product Overview

The ADXL372 is an ultralow power, 3-axis, ±200 g MEMS accelerometer that consumes 22 μA at a 3200 Hz output data rate (ODR). The ADXL372 does not power cycle its front end to achieve its low power operation and therefore does not run the risk of aliasing the output of the sensor.

In addition to its ultralow power consumption, the ADXL372 has many features to enable impact detection while providing system level power reduction. The device includes a deep multimode output first in, first out (FIFO), several activity detection modes, and a method for capturing only the peak acceleration of over threshold events.

Two additional lower power modes with interrupt driven, wake-up features are available for monitoring motion during periods of inactivity. In wake-up mode, acceleration data can be averaged to obtain a low enough output noise to trigger on low g thresholds. In instant on mode, the ADXL372 consumes 1.4 μA while continuously monitoring the environment for impacts. When an impact event that exceeds the internally set threshold is detected, the device switches to normal operating mode fast enough to record the event.

High g applications tend to experience acceleration content over a wide range of frequencies. The ADXL372 includes a 4-pole low-pass antialiasing filter to attenuate out of band signals that are common in high g applications. The ADXL372 also incorporates a high-pass filter to eliminate initial and slow changing errors, such as ambient temperature drift.

The ADXL372 provides 12-bit output data at 100 mg/LSB scale factor. The user can access configuration and data registers via the serial peripheral interface (SPI) or limited I2C protocol. The ADXL372 operates over a wide supply voltage range and is available in a 3 mm × 3.25 mm × 1.06 mm package.
