GENERAL DESCRIPTION
The ADIS16223 iSensor® is a tri-axial, digital vibration sensor system that combines industry-leading iMEMS® sensing technology with signal processing, data capture, and a convenient serial peripheral interface (SPI). The SPI and data buffer structure provide convenient access to wide bandwidth sensor data. The 22 kHz sensor resonance and 72.9 kSPS sample rate provide a frequency response that is suitable for machine-health applications. The programmable digital filter offers low-pass and band-pass configuration options.
