The SPI and data buffer structure provide convenient access to wide-bandwidth sensor data. 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 controls for lower bandwidth applications. An interna...
