The SPI and data buffer structure provide convenient access to wide-bandwidth sensor data. The 22 k Hz sensor resonance and 100.2 k SPS sample rate provide adequate response for most machine-health applications. The averaging/ decimating filter provides optimization controls for lower bandwidth applications. An internal clock drives the data sampling system, which fills the buffer memory for user access. The data capture function has three different trigger modes. The automatic data collection allows for periodic wake-up and capture, based on a programmable duty cycle. The manual data capture mode allows the user to initiate a data capture, providing power and read-rate optimization. The event capture mode continuously updates the buffers and monitors them for a preset trigger condition. This mode captures...
