GENERAL DESCRIPTION
The ADIS16240 is a fully integrated digital shock detection and recorder system. It combines industry-leading iMEMS® technology with a signal processing solution that optimizes dynamic performance for low power applications. The triple-axis sensing element enables shock measurement in all directions, eliminating the need for additional sensors and complex mechanical structures for many applications. The digital serial peripheral interface (SPI) uses four wires and is compatible with most processor platforms. The SPI interface provides access to sensor data and a set of configuration registers that control such operational parameters as offset bias correction, sample rate, sleep mode, peak detection, and event capture.
