GENERAL DESCRIPTION
The ADIS16220 iSensor® is a digital vibration sensor that combines industry-leading iMEMS® sensing technology with a signal processor. It provides a buffer memory for high speed data capture, along with a convenient serial interface for data collection and configuration. The 22 kHz sensor resonance and 100.2 kSPS sample rate provide adequate response for most machine-health applications. The averaging/decimating filter provides optimization for lower bandwidth applications.
