gle-supply operation: 3.15 V to 3.6 V Op erating temperature range: −40°C to +125°C 9.2 mm × 9.2 mm 16-terminal LG A Programmable Digital Vibration Senso r ADIS16220 GENERAL DESCRIPTION The ADI S16220 iSensor® is a digital vibration sensor that combines industry-leading iMEMS® sensing technology with a signa l processor. It provides a buffer memor y for high speed data capture, along wi th a convenient serial interface for da ta collection and configuration. The 22 kHz sensor resonance and 100.2 kSPS sa mple rate provide adequate response for most machine-health applications. The averaging/decimating filter provides op timization for lower bandwidth applicat ions. An internal clock drives the data sampling system, which fills the buffe r memory for user access. The data capt ure function has three different trigge r modes. The automatic data collection allows for periodic wake-up and capture , based on a programmable duty cycle. T he manual data capture mode allows the user to initiate a data capture, provid ing power and read-rate optimization. T he event capture mode continuously upda tes the buffers and monitors them for a preset trigger condition. This mode ca ptures pre-event data and post-event da ta and produces an alarm indicator for driving an interrupt. The serial peripheral interface (SPI
