Product Details

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 perfor-mance 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 config-uration registers that control such operational parameters as offset bias correction, sample rate, sleep mode, peak detection, and event capture.

The programmable event recorder offers two trigger modes. The internal mode monitors continuous sampled data and triggers the capture, based on the user-defined threshold. The external mode uses the two comparator inputs and a user-defined threshold to trigger the event captures. This function also provides user configuration controls for capture length, pretrigger data, and data storage. Each event is stored with a header that captures temperature, power supply, and time. Several power management features, including sleep mode and a wake-up function, enable power optimization with respect to specific mechanical system requirements.

<> The ADIS16240 is available in a 12 mm × 12 mm laminate-based ball grid array (BGA) that meets IPC/JEDEC standards for Pb-free solder reflow processing (J-STD-020C and J-STD-033).
