APPLICATIONS Impact detection Condition monitoring Safety Systems Shock sensor GENERAL DESCRIPTION The ADIS16204 is a programmable impact sensor in a single pact package enabled by the Analog Devices i Sensor™ integration. By enhancing the Analog Devices i MEMS® sensor technology with an embedded signal processing solution, the ADIS16204 provides tunable digital sensor data in a convenient format that can be accessed using a serial peripheral interface (SPI). The SPI interface provides access to measurements for dual-axis linear acceleration, a root-sum-square (RSS) of both axes, temperature, power supply, and one auxiliary analog input. Easy access to digital sensor data provides developers with a system-ready device, reducing development time, cost, and program risk. Unique characteristics of the end system are acmodated easily through several built-in Features , such as a single mand in-system offset calibration, along with...
