GENERAL DESCRIPTION

The ADIS16204 is a fully-contained programmable impact sensor in a single compact package enabled by the Analog Devices, Inc. iSensor™ integration. By enhancing the Analog Devices iMEMS® 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 provides access to measurements for dual-axis linear acceleration, a root sum square (RSS) of both axes, temperature, power supply, an auxiliary analog input, and an event capture buffer memory. Easy access to digital sensor data provides users with a system-ready device, reducing development time, cost, and program risk.
